Question

A switch controls the current in a circuit that has a large inductance. The electric arc at the switch (Fig. CQ32.3) can melt and oxidize the contact surfaces, resulting in high resistivity of the contacts and eventual destruction of the switch. Is a spark more likely to be produced at the switch when the switch is being closed, when it is being opened, or does it not matter

Answer 1

When the circuit is opened, a spark is much more possible.

What is an inductor?

The primary purpose of an inductor is the storage of energy. This is why an inductor helps to eliminate a spark in a circuit.

In the circuit as described in the question, we know that there is no current when the circuit is closed, the current across the inductor remains constant but rapidly decreases at the opening of the circuit this could lead to a spark.
