Hair dryers can run off one typical household circuit
Not what you're looking for?
Part 1
A typical household circuit is capable of carrying 15.0 Amps of current at 120 V before the circuit breaker will trip. How many 1500-W hair dryers can run off one such circuit?
Part 2
In the rush to get ready for lecture, a physics professor leaves the hair dryer described in the previous problem running and does not turn it off until he gets home 8.0 hours later. How much will this add, in dollars, to his next electric bill (assume electricity costs $0.078 per kilowatt-hr)?

This is how you may proceed to solve it,
Part 1
Power = V I
I = Power / Voltage
= 1500 Watt / 120 Volt
= 12.5 A
