What power in kw is required to transfer a charge of 9000 coulomb through a potential difference of 220 volts in 45 min?
0.9 kw
0.73 kw
0.5 kw
1.6 kw

The power is 0.73 kW.

(B) option is correct.

Explanation:

Given that,

Charge = 9000 C

Potential difference = 220 V

Time = 45 min

We need to calculate the energy required to transfer charge Q through V

Using formula of energy

Put the value into the formula

We need to calculate the power

Using formula of power

Hence, The power is 0.73 kW.
