Solved: When a certain resistor is connected to an ac
Chapter 24, Problem 84(choose chapter or problem)
When a certain resistor is connected to an ac generator with a maximum voltage of 15 V, the average power dissipated in the resistor is 22 W. (a) What is the resistance of the resistor? (b) What is the rms current in the circuit? (c) We know that , and hence it seems that reducing the resistance should reduce the average power. On the other hand, we also know that , which suggests that reducing R increases . Which conclusion is correct? Explain
