Walker, Halliday & Resnick β Electromagnetic Oscillations and Alternating Current: Problem 44
44 An ac generator has emf \(\mathcal{E} = \mathcal{E}_m \sin \omega_d t\), with \(\mathcal{E}_m = 30.0 \text{ V}\) and \(\omega_d = 377 \text{ rad/s}\). It is connected to a \(12.7 \text{ H}\) inductor. (a) What is the maximum value of the current? (b) When the current is a maximum, what is the emf of the generator? (c) When the emf of the generator is \(-15.0 \text{ V}\) and increasing in magnitude, what is the current?
π Solution Approach
Find: (a) What is the maximum value of the current?; (b) When the current is a maximum; (c) When the emf of the generator is \
