FAQ

Those who are looking for an answer to the question «Unit of electric power can also be expressed as?» often ask the following questions:

👉 What is the unit of electric power?

There is nothing like “1 unit electricity”. Throughout the world there is one type or another type of measurement which has been taken as a base amount of electric power. 1KWh is a mainly used unit of power. It is the amount of electric power consumed in 1 hour by an electric appliance of 1000 W (1KW). FAQs (Frequently Asked Questions)

👉 What is the practical unit of electric power?

watt

The watt (symbol: W) is a unit of power or radiant flux. In the International System of Units (SI), it is defined as a derived unit of (in SI base units) 1 kg⋅m2⋅s3 or, equivalently, 1 joule per second. It is used to quantify the rate of energy transfer.

👉 Which is not the unit of electric power?

The commercial unit of electrical energy is the kilowatt-hour (kWh) which is also knwon as the Board of trade unit (B.O.T). 1 kwh = 1000 × 60 × 60 watt – second 1 kwh = 36 × 10 5 Ws or Joules Generally, one kwh is called one unit.

Power can be expressed in many different units, all of which can be expressed as a unit of energy divided by a unit of time. The most common unit is the watt (W), defined as 1 joule (J) of energy per second. A 40 W light bulb, then, uses 40 J of electrical energy every second to stay lit.

The SI unit of power is the watt, one joule per second. Electric power is usually produced by electric generators, but can also be supplied by sources such as electric batteries. It is usually supplied to businesses and homes (as domestic mains electricity) by the electric power industry through an electric power grid.

The rate at which the heat is dissipated is called power, and is measured in units of watts ( W ). To find the power (P) using V and I, we use P = V I. Here, the unit of Voltage (V) is volt and Current (I) is ampere. Hence, the unit of electric power can also be expressed as volt ampere.

V = Voltage measured in volt. I = Current measured in ampere. ∴ The unit of electric power can also be expressed as volt-ampere. Kilowatt-hour – Unit of energy which is equal to 1-kilowatt power which is sustainable for an hour.

The unit of electric power may also be expressed in joule second. Explanation: The standard unit of electric power is watt and kilowatt. the amount of electric power which is consumed per hour is given by kilowatt hour. joule second is another common unit which is used in place of kilowatt hour.

Unit of electric power may also be expressed as: (i) volt-ampere (ii) kilowatt-hour (iii) watt-second. ← Prev Question Next Question →. +1 vote.

Unit of electric power may also be expressed as (a) volt ampere (b) kilowatt hour (c) watt second (d) Joule second. Answer. Answer: (a) volt ampere

Electric power is the rate at which work is done or energy is transformed into an electrical circuit. Electric power is measured in watts. Learn its definition, formula, unit along with solved examples at BYJU'S.

Also, volt can be expressed as the potential difference that exists between two points in an electric circuit which imparts an energy of 1 joule (J) per coulomb of charge that flows through the circuit. V = potential energy/ charge. V = J/ C = Kg m²/ A s³. It can also be expressed as ampere times ohm, joule per coulomb or watt per ampere.
