The electric field established by a generator in an ac circuit
A)increases via the inverse-square law.
B)changes magnitude and direction with time.
C)acts in one direction.
D)is non-existent.
E)none of the above

Question

Quizplus · Accepted Answer

An AC circuit has a changing current and therefore a changing magnetic field, which in turn creates a changing electric field. This electric field changes both in magnitude and direction with time, and can be represented by a sinusoidal wave. Therefore, option B is the correct choice. Options A, C, and D are incorrect as they do not accurately describe the behavior of the electric field in an AC circuit.
