What is Moore’s Law?Moore’s Lawrefers to the observation that the number oftransistorsin anintegrated circuit(IC) doubles approximately every 2 years. It is often cited as an explanation for the exponential growth of technology, sometimes even being coined as the ‘law of exponential growth’.Moore’s law is named after Gordon Moore, the co-founder of Intel. Moore observed that since the invention of integrated circuits, the number of transistors has doubled every year. Moore produced an article in

What is Watts Law?Watt’s law defines the relationship between power, amperage, and voltage drop in an electrical circuit. Watts Law also states that the power of an electrical circuit is the product of its voltage and current.Watts Law FormulaThe formula for Watts law can be given as follows. It gives the relationships between power (watts), current (amps) and voltage(volt)Watts Law Example 1Suppose you were trying to find out how many 500-watt lighting devices you could plug into a circuit with

magine afeeder pillaras the unsung hero in your neighborhood, ensuring electricity flows safely to every home. This crucial cabinet, often seen but rarely noticed, orchestrates the distribution of power, safeguarding circuits and simplifying control. It’s like the brain of your area’s electrical system, quietly keeping the lights on and appliances running smoothly.Similar to ajunction box, a feeder pillar box protects people from coming into contact with live wires, as well as protecting wires f

The Seebeck effect is a phenomenon that converts temperature differences into electric voltage and vice versa. It is named after Thomas Johann Seebeck, a German physicist who discovered it in 1821. The Seebeck effect is the basis of thermocouples, thermoelectric generators, and spin caloritronics. What is the Seebeck Effect?The Seebeck effect is defined as the generation of an electric potential (or voltage) across two different conductors or semiconductors that are connected in a loop and have

What is a Multimeter?A multimeter, also known as amultitesterorVOM(Volt-Ohm-Milliammeter), is an electronic measuring instrument used to measure various electrical parameters.Multitesters are a standard diagnostic tool for technicians and electricians in the electrical & electronic industries (see the fulllist of electricians tools).A typical multimeter can measure voltage, current, and resistance. Thebest multimeterscan also measure other electrical characteristics such as continuity, frequ

Consider a RLC circuit in which resistor, inductor and capacitor are connected in parallel to each other. This parallel combination is supplied by voltage supply, VS. This parallel RLC circuit is exactly opposite to series RLC circuit.In series RLC circuit, the current flowing through all the three components i.e the resistor, inductor and capacitor remains the same, but in parallel circuit, the voltage across each element remains the same and the current gets divided in each component depending

Consider a RLC circuit in which resistor, inductor and capacitor are connected in series across a voltage supply. This series RLC circuit has a distinguishing property of resonating at a specific frequency called resonant frequency.In this circuit containing inductor and capacitor, the energy is stored in two different ways. When acurrentflows in an inductor, energy gets stored inmagnetic field. When a capacitor is charged, energy gets stored in static electric field.The magnetic field in the in

A junction box – also known as an ‘electrical box’, ‘jbox’, ‘or ‘terminal box’ – is a protective box where wires are interconnected. Junction boxes are often built into the plaster of a wall, in the ceiling, or within concrete. They are standard within most homes, buildings, and factories.Junction boxes are found both indoors and outdoors. Waterproof junction boxes are commonly used outdoors.Junction boxes are typically made of metal or plastic. There 4 main electrical junction box types: Metal

What is a Series RLC Circuit?A series RLC circuit is one the resistor, inductor and capacitor are connected in series across a voltage supply. The resulting circuit is called series RLC circuit. A circuit and phasor diagram for a series RLS circuit has been shown below.Phasor Diagram of Series RLC CircuitThe phasor diagram of series RLC circuit is drawn by combining the phasor diagram of resistor, inductor and capacitor. Before doing so, one should understand the relationship between voltage and

In an RLC circuit, the most fundamental elements of a resistor, inductor, and capacitor are connected across a voltage supply. All of these elements are linear and passive in nature. Passive components are ones that consume energy rather than producing it; linear elements are those which have a linear relationship between voltage and current.There are number of ways of connecting these elements across voltage supply, but the most common method is to connect these elements either in series or in
