1) A resistor dissipates 2.00 W when the rms voltage of the emf is 10.0 V. At what rms voltage will the resistor dissipate 10.0 W?
2) A 100? resistor is connected to a 120 V/60 Hz power line. What is the average power loss?
3) In an Ac circuit, the rms current through a resistor is 0.80 A. What is the peak current?
