Question

Which equation is used to calculate the amount of electrical energy used?

a) E = t ÷ P

b) E = t – P

c) E = P + t

d) E = P × t

Answer 1

d
cause E=U and in power formula is p=U÷t or E÷t so E=p×t

Answer 2

The equation of amount of electrical energy used
`E = P* t`.

d is correct option.

Step-by-step explanation:

Electrical energy :

The electrical energy is the chemical energy which is consumed in the electric circuit.

Power :

Electric power is the rate at which energy is transferred from one part to another part of electric circuit.

The amount of electric energy is defined as,

The amount of electrical energy is the product of the power and time.

`E = P* t`

Where, E = energy transferred

P = Power

t = time

Hence, The equation of amount of electrical energy is used
`E = P* t`.
