Meen different coloured wires in the electric circuit used for?
Different 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.
Meen transistors made of?

Meen tools used needed to measure various electrical parameters in an electrical circuit?
Following is the list of some measuring tools used for the measurement of electrical parameters:
Voltmeter
Ammeter

Define Multimeter?
Multimeter yana nufin electronic device da ake amfani don test circuit resistance, amps, da voltage. Engineers can test voltage, resistance, and electrical current levels with mustimeters by connecting two leads to various electrical system components.
Meen 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.
what is NO and NC contact?
NC means normally-closed contact. NO means normally-open contact.
How does NC contact work?
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.
