Question

An electric fan connected to a 220 V source. the current is 4A what is the power of the fan​

Answer 1

Voltage V=220V

Current I=4A

Now, rate at which the electrical energy transformed

P=V×I

P=220×4

P=880 watts

Now, the energy is transformed in 2 min

P=tE

E=P×t

E=880×120

E=105600J

Hence, the energy transformed is 105600 J
