(A) The maximum power that can be drawn from the supply is given by $P_{total} = V 	imes I$.Given $V = 220 \,V$ and $I = 5 \,A$,we have $P_{total} = 220 	imes 5 = 1100 \,W$.Let $n$ be the number of bulbs of power $P_1 = 60 \,W$ that can be run safely.Then,$n 	imes P_1 \leq P_{total}$.$n 	imes 60 \leq 1100$.$n \leq \frac{1100}{60} = 18.33$.Since the number of bulbs must be an integer,the maximum number of bulbs that can be safely run is $18$.

How many $60 \,W$ bulbs may be safely run on $220 \,V$ using a $5 \,A$ fuse?
