A circuit breaker is rated for a current of 15 A rms at a voltage of 120 V rms. Answer the following questions:
All answers must have three significant digits unless otherwise specified.
1) What is the largest value of I(max) that the breaker can carry? (Unit: A)
answer:
I(max) = 15(rms) / square root of 2
= 10.6A
2) What average power can be supplied by this circuit? (Unit: kW)
P(rms) = I (rms) * V (rms)
= 1.80 kW
pls correct me if I was wrong and pls direct me to the right path...
thanks
