An emf Epsilon_L is induced in an inductor coil. Which of the following choices can describe the current through the coil if the emf points to the right? (Multiple answers are possible.) Explain. Constant and rightward. Constant and leftward. Increasing and rightward. Decreasing and rightward. Increasing and leftward. Decreasing and leftward.

Solution

The direction of induced emf is opposite to the change in current in the coil.

We know induced emf E = -L di/dt

Where L = inductance

     di / dt = rate of change of current

So, answers are , increasing and leftward ,

                         decreasing and rightward
