A typical household circuit is capable of carrying 30.0 A of current at 120 V before the circuit breaker will trip. How many 1500-W hair dryers can run off one such circuit?
Use the relation between power, current and voltage. Also, remember hair dryers come in integer units.
P = VI
The Attempt at a Solution
P = 120 * 30 = 3600
3600/1500 = 2.4
This is incorrect and I don't understand why. Am I missing something?
