(a) Define Electric power. Express electric power of an electric appliance in terms of its resistance (R) and the voltage / potential difference (V) at which it operates. (b) The rated voltage of an air-conditioner is 220 V. This air-conditioner consumes 22 units of electric energy in 10 hours, calculate :
- (i)Power rating of the air-conditioner,
- (ii)Current drawn by the air-conditioner, and
- (iii)Resistance of the air-conditioner
