1. Outlets of two rooms are placed in parallel on a single circuit (120 volts). How many 100 watt light bulbs could you run on a circuit that had a 15 amp circuit breaker (max of 15 amps total)

need help setting up problem??

Each 100 W lamp draws I = P/V = 100/120 = 0.83 Amps, if 120 volts is applied to it. The number of lamps it takes to use a total of 15 Amps is therefore ___

Don't be confused by the number of rooms. And don't assume the lamps are in series. They are all in parallel from a power line with a single circuit breaker.
