A light bulb is rated at 60 W when used with a 120 V power line. If multiple 60 W light bulbs are to be connected together in parallel, what is the maximum number that can be in parallel without exceeding the 13 A limit of their circuit breaker? Hint: the total current through the parallel circuit is equal to the sum of the currents through each bulb.
