... 1. (3 points) What would happen if the electric field in an ideal conductor is not zero? Ans: Since there is an infinite amount of charges assumed for an idea conductor, an electric field in a conductor will maintain a current until the net internal field settles to zero. 2. (3 points) For a surface ...

... currents in this circuit vary sinusoidally at this frequency. An external source—possibly an ac generator—must be included to supply energy to compensate both for thermal losses in the circuit and for energy carried away by the radiated EM wave. The LC oscillator is coupled by a transformer and a tr ...
