What happens when the low-voltage current flow in the coil primary winding is interrupted by the switching device?
A)The magnetic field around the primary winding collapses
B)The movement of the magnetic field across the winding induces a high voltage in the secondary winding
C)Both A and B
D)Neither A nor B

Question

Quizplus · Accepted Answer

When the low-voltage current flow in the coil's primary winding is interrupted, the magnetic field around the primary winding collapses. This change in the magnetic field induces a high voltage in the secondary winding due to electromagnetic induction. Therefore, both A and B are correct.
