Unsa ang pagkakaiba sa pagitan sa Fuse ug Breaker?
Ang fuse adunay wire nga matutugok kung ma-expose sa init sa short circuit o mataas nga current, samtang nag-interrupt sa circuit. Kinahanglan nimong paliton human matutugok.
Ang circuit breaker nagsilbi sa pag-cut off sa current walay matutugok (isip e.g., duha ka metal sheets nga adunay di parehas nga thermal expansion coefficients) ug mahimo mosabot.
Unsa ang Circuit?
Ang mga koneksyon sa incoming wires gihimo sa sulod sa panel. Ang mga koneksyon kini gigamit aron maghatag og power sa partikular nga areas sa balay.
Unsa ang CSA approval?
Bago mabenta ang electrical equipment o component sa Canada, kinahanglan na siya certified sa Canadian Standards Association (o usa ka recognized equivalent). Kini nag-imply na ang tanang wiring kinahanglan gamiton ang CSA-approved materials. Gihimo nila ang testing similar sa UL (aing mas stringent), pero ang CSA (o recognized equivalent) clearance ang gipangutana sa batas.

Unsa ang NEC?
NEC stands for National Electrical Code. Refer to our page on the NEC for more details.
Pila ang electric traction?
Traction refers to the use of electric power for traction systems, such as trolleys, trams, and railroads. Electric traction all refers to the use of electricity. Today’s bullet trains also use magnetic traction. Basically, electric traction systems use dc motors.
Unsa ang encoder ug unsa ang iyang function?
An encoder is a device that converts a signal or data into a code, like a bitstream. The code may be used for a variety of things, including compressing data for storage or transmission, encrypting the input code, adding redundancies, or translating between different codes. When any component is digital, this is often accomplished using a pre-programmed algorithm, whereas analogue encoding is typically accomplished using analogue circuitry.
Unsa ang operation sa motor?
Torque is the term for the turning or twisting motion that is produced whenever a current-carrying conductor is placed in a magnetic field.
Unsa ang mahitabo kung hatagan nato ang bulb o tube light ngadto sa 220-volt direct current supply?
Since bulbs are made to run on AC, the AC supply has a high impedance. They typically have little resistance. Low resistance causes the current through a lamp to be so high when a DC supply is supplied that it could harm the bulb.
Describe ACSR cable.
Aluminium conductor steel reinforced, or ACSR, is the name of the conductor used in transmission and distribution.
In case of a D.C shunt motor under no load condition the air gap flux
In shunt motor,
Ish = V / Rsh.
If V is constant Ish will also be a constant. Hence the flux is constant
A moving coil ammeter with a coil with resistance of 1000 ohms has a full-scale deflection of 50. To increase the range to 1 A, the shunt resistance must be _ ohms.
0.05.
Unsa ang pagkakaiba sa capacitance ug inductance?
Capacitance: Capacitance is defined as the amount of charge stored inside a capacitor at a fixed voltage.
Inductance is a coil’s ability to resist changes in the electric current running through it. Mutual inductance occurs when the current change in the primary coil is opposed by a secondary coil.
Unsa ang mahitabo kung duha ka positively charged elements kombinado?
Positives repel and opposites attract. When two positively charged elements are placed next to each other, they repel and move away from each other.
Unsa ang pagkakaiba sa capacitor, resistor, ug inductor?
Capacitor: A capacitor is an electrical component that serves as a passive element by opposing current flow. When a potential is applied, it also stores some type of electrical charge.
Resistor: A resistor is an electrical component that obstructs the flow of current. It is a two-terminal component that is mostly used to minimise current flow.
Inductor: An inductor is an electrical component that stores energy in the form of a magnetic field and is used to build electrical circuits. It is also known as a choke or a coil.
Unsa ang two-phase motor?
A two-phase motor is one that features a phase split between the starting and running windings.
Unsa ang armature reaction?
The reaction of armature flu to main flux is known as armature reaction. The armature flux can either assist or oppose the main flux.
Unsa ang circuit breaker?
A circuit breaker is a device that may break a circuit manually or automatically under all conditions, including no load, full load, and short circuit.
Name the types of circuit breakers?
AC Circuit Breaker
DC Circuit Breaker.
Unsa ang ELCB?
ELCB is an abbreviation for Earth Leakage Circuit Breaker. They serve the same purpose as RCCBs but are voltage sensor devices.
Unsa ang MCB?
Miniature Circuit Breakers are abbreviated as MCBs. The MCB is an electromechanical device that immediately shuts down the circuit whenever an irregularity is detected.
Unsa ang MCCB?
MCCB stands for Molded Case Circuit Breaker. The MCCB is a device that protects the circuit against overloading. It also includes a manually operated switch for tripping the circuit.
Unsa ang RCCB?
RCCB is an abbreviation for Residual Current Circuit Breaker. This residual current device is essentially an electrical wiring device that disconnects the circuit anytime current leaks through the human body or current is not balanced between the phase conductors.
Unsa ang RCD?
An RCD, or residual current device, is a life-saving mechanism that prevents you from receiving a deadly electric shock if you come into contact with something live, such as a bare wire. It can also help to protect against electrical fires.
Unsay reversal polarity?
Reverse polarity happens when the wires are not properly connected. For instance, suppose the white wire is connected to the hot side and the black wire is connected to the neutral side.
Asa ang mahimo para mapasabot ang reverse polarity?
You can resolve reverse polarity issue by inspecting the wire connection from the outlet or the receptacle. By exchanging this entanglement, you can solve the reverse polarity.
Unsa ang mga kaibahan sa mga kulay sa wires sa electric circuit?
The various sorts of coloured wires in an electric circuit define the various duties they perform. In the electric circuit, there are seven different sorts of coloured wires that each serve a specific purpose.
Black wire: The black cable is the primary power supply source in the electric circuit. This is not applicable to ground wires. It is used in either the hot or living state.
Green wire: This wire connects to the ground terminal. Green wires can be found in an outlet box.
Red wire: The second principal wire is the red wire. It is used to relay the wire’s live state. It can be utilised in various types of linkages and is present in a 220-volt circuit. Furthermore, it can be connected to either another red or a black wire.
White/Gray: The neutral wire is white or grey. It transports the unbalanced load to the terminal. This wire’s terminus is placed in the ground. This wire can connect to other wires of the same type.
Blue/Yellow: Power is carried by the blue or yellow wires; hence they are used as live wires. In general, most gadgets lack these wires.
Unsa ang transistors gihimo?

Define Multimeter?
A Multimeter is an electronic device used to test circuit resistance, amps, and voltage. Engineers can test voltage, resistance, and electrical current levels with mustimeters by connecting two leads to various electrical system components.
Unsa ang short circuit?
When two or more wires supplying electrical power to the device come into contact with each other, current flows in an unanticipated channel.
In other terms, a short circuit occurs when the phase and neutral wires come into direct contact with each other without any load attached between them.
Unsa ang NO ug NC contact?
NC means normally-closed contact. NO means normally-open contact.
Asa ang function sa NC contact?
A NC contact, also known as a normally closed contact, performs the same purpose as a NO contact. It remains closed unless a specified criteria is met. An illustration of limit switch operation in this case. When the actuator of a limit switch is pressed, its NC contact, which is used in a circuit, interrupts the circuit or current flow. Similarly, until the coil of a relay is activated, its contacts are permanently closed.
Asa ang function sa NO contact?
A NO contact or a normally open contact is one that remains open until a specified criteria is met. As an example, consider a limit switch. At least one NO contact must be present in a limit switch. The NO contact of the limit switch remains open until the actuator is depressed. When the actuator is depressed, the contact closes and conducts. When it comes to proximity switches, NO contacts remain open until they detect an interruption, whereas pressure switches remain open until the predetermined pressure threshold is exceeded.
