potential difference : 230 v

current : 0.4 A

rate at which energy flow = ?

Energy = power ,

power = potential difference × current

so, p = 230 × 0.4

= 92

Answer:

92 J/s

Explanation:

Voltage of the fan = V = 230V (Given)

Current flowing through the fan = I = 0.4 A (Given)

The rate at which electric energy is transferred is known as power.

Thus, as per the formula of power -

P = V x I

= 230 x 0.4

= 92

= 92 J/s

Therefore,  the rate at which the electrical energy transferred by the fan is 92 J/s
