When it comes to the SI unit of electricity, the unit of power is Watt. So, if you've ever wondered what the unit of electricity is, the answer is below. The unit, in this case, reflects the actual measure of electricity or the amount of energy consumed at a location. If you've ever looked at an electricity bill, you'll notice that the unit of electricity is usually expressed in kilowatt-hours (kWh). It is the amount of electric power consumed in 1 hour by an electric appliance of 1000 W (1KW).Įlectricity is Measured in Units of Electricity. Throughout the world, there is one type or another type of measurement which has been taken as a base amount of electric power. There is nothing like “1 unit electricity”. The Units of Electric Charge are Listed in The Table Mentioned Below A coulomb is defined as an ampere second. The SI unit of electric charge is the coulomb. It is the time taken by the output to reach 63.7% of its minimum or maximum value when subjected to step response input. Τ – Time Constant, The Time Constant is a characteristic of an impedance circuit. Ω – Angular Frequency is used in AC circuits to represent phase relation between two waveforms. It is a time difference that depends upon the circuit element. It is the difference (in degrees) between the voltage waveform and the current waveform, which have the same time period. It is used to represent a gain in voltage, power or current. For example, a normal electric bulb consumes 100 watts of power per hour.ĭB – A Decibel is a one-tenth unit of Bel (symbol B). Wh – The Watt-Hour is defined as the amount of electric energy consumed by an electric circuit over a given time duration. Just like the standard units, other units are used to denote the values and quantities. Power (P)/Watts (W) - Power is defined as the product of the work required and the number of electrons passing through the circuit per unit time. Resistance (R) /Ohms (O) - Resistance is the opposition offered to the flow of current in a circuit. Voltage/Volts (V) - The amount of work required to move an electric charge from one point to another is called voltage.Ĭurrent (I)/Amps (A) - Current is defined as the amount of charge (or electrons) passing through a circuit per unit of time. While converting one prefix to another, we have to multiply or divide the difference between the two values. 1MHz = 1 mega-hertz = one million Hertz.
