An air conditioner of 2kW is used in an electric circuit having a fuse of 10A rating. If the potential difference of the supply is 220 V will the fuse be able to withstand, when the air conditioner is switched on ? Justify your answer.

<P>

SOLUTION :Here P = 2k W = 2000 W, V = 220 Volt
P = VI, the current I = `(p)/(V) = (2000)/(220) = 9.09 ` A
As the current is 9.09 A, below the rating of fuse, the fuse will withstand i.e., it will not blow off when AC is on.
