What might be a problem with the bimetallic strip type of circuit breaker shown in the figure?
Homework Answers
There is a possibility of several issues with the bimetallic circuit breaker. But most dominant out of these will be flow of overcurrent due to inappropriate rating of circuit breaker used. Also the terminal connection of the appliances might be in wrong order too.

A 1500 W electric heater is plugged into the outlet of a 120 V circuit that has a 20 A circuit breaker. You plug an electric hair dryer into the same outlet. The hair dryer has power settings of 600 W, 900 W , 1200 W, and 1500 W. You start with the hair dryer on the 600 W setting and increase the power setting until the circuit breaker trips. Under what setting does the circuit breaker trip. Please, no...

A typical household circuit is capable of carrying 30.0 Amps of current at 120 V before the circuit breaker will trip. How many 1500-W hair dryers can run off one such circuit? Tries 0/10 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 7.9 hours later. How much will this add, in dollars, to his next electric bill...
