An electric fan runs from the V = 230 V mains. The current flowing through it is 0.4 A. At what rate is electrical energy transferred by the fan?

Given Data:
• Voltage (V) = 230 V
• Current (I) = 0.4 A
To Find:
The rate at which electrical energy is transferred by the fan, i.e., the power (P) consumed by the fan.
Solution:
The power consumed by an electrical appliance can be calculated using the formula:
P=V×IP = V \times I
Where:
• PP is the power (rate of energy transfer),
• VV is the voltage across the appliance,
• II is the current flowing through the appliance.
Substituting the given values:
P=230 V×0.4 AP = 230 \, \text{V} \times 0.4 \, \text{A} P=92 WP = 92 \, \text{W}
Conclusion:
The rate at which electrical energy is transferred by the fan is 92 watts (W).
