Question

Unit of electric power may also be expressed as:

i) volt-ampere

ii) kilowatt-hour

iii) watt-second

iv) joule-second​

Answer 1

Volt-ampere is the correct answer to this question.

Explanation:

Volt-ampere:-

• As a current flows through such a resistor, it transforms electrical energy into heat. The heat produced in electronic circuits, all of which possesses good some resistance, is drained away from around modules into the air. The rate of dissipation of the heat is called power and is expressed in meters of watts ( W).

• We use P = VI to find the Power (P) with V and I. The Voltage (V) unit here is volt and Current (I) is ampere.

    Thus, the electric power unit can also be expressed as a volt-ampere.

• This same rate of dissipation of the high temperatures is called power but is expressed in meters of watts ( W). We use P = VI to find this same Power (P) with V and I. The Voltage (V) unit here is volt and Current (I) is ampere. Thus, the electricity generation unit could also be conveyed as a volt-ampere.

Other options are incorrect because they are not related to the given scenario.
