Question

when electromagnetic relays are de - energized, the collapse of the magnetic field induces a large voltage spike in the relay coil windings. select one: true false

Explanation:

When electromagnetic relays are de - energized, the rapid collapse of the magnetic field (due to the change in current) induces a large voltage spike in the relay coil windings according to Faraday's law of electromagnetic induction. This is a well - known phenomenon in electrical circuits involving inductive elements like relay coils.

Answer:

True
