Solution
Power P = VI = 2000 W
V = 220 V
Current drawn I = P/V = 2000 W/220 V = 9.09 A
The current drawn by the air conditioner is 9 A , which is much greater than the capacity of the fuse in the circuit, i.e., 5 A. So when a high current of 9 A flows through the 5 A fuse, the fuse wire will get heated to such an extent that it melts and breaks the circuit, cutting off the power supply. Hence when an air conditioner of rating 2000 W; 220 V is operated in a domestic circuit that has a current rating of 5 A, the fuse will blow off cutting off the power supply in the circuit
