A battery and a resistor are wired into a circuit. The resistor dissipates 0.50 W. Now two batteries, each identical to the original one, are connected in series with the resistor. What power does it dissipate?

A battery and a resistor are wired into a circuit. The resistor dissipates 4.0 W. Now the resistor is replaced with one that has twice the original resistance. What power does the new resistor dissipate?

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. What power setting caused the breaker to trip?
