A 1500-WW electric heater is plugged into the outlet of a 120-VV circuit that has a 20-AA circuit breaker. You plug an electric hair dryer into the same outlet. The hair dryer has power settings of 600 WW, 900 WW, 1200 WW, and 1500 WW. You start with the hair dryer on the 600-WW setting and increase the power setting until the circuit breaker trips.?

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 3.00 ms . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
