Question

an electric fan run from the 220 volt.the current flowing through it is 0.6 ampere at what rate is the electric energy transformed at fan.how much energy is transformed in two minute
​

Answer 1

Answer:

Given that,

Voltage V=220V

Current I=0.6A

Now, rate at which the electrical energy transformed

P=V×I

P=220×0.6

P=132 watt

Now, the energy is transformed in 2 min

P= E/t

E=P×t

E=132×120

E=15840J

Hence, the energy transformed is 15840J
