In household wiring, the outlets of two rooms are placed in parallel on a single circuit. How many 100 Watt light bulbs could you run on a circuit that had a 15 amp circuit breaker (maximum of 15 amps total)?

  • Power = (voltage) x (current)
  • Power = (voltage) x (15 Amperes)

In the United States and Canada:  Voltage = 120 V

Power = (15 Amperes) x (120 V)

Power = 1,800 watts

You could run a grand total of 18 light bulbs on that circuit, with not a single electron to spare.


In Africa, Israel, Europe:  Voltage = 240 V

Power = (15 Amperes) x (240 V)

Power = 3,600 watts

You could run a grand total of 36 light bulbs on that circuit, with not a single electron to spare.
