Definitions:

Spike Suppression

Techniques or devices used to protect electronic circuits from sudden transient voltages, which could cause damage or malfunction.

Metal Oxide Varistor

A voltage-dependent resistor with a nonlinear variance, used to protect electrical circuits from voltage spikes.

Inductance

The property of an electrical conductor by which a change in current flowing through it induces an electromotive force in both the conductor itself and in any nearby conductors by mutual inductance.

Wire Resistance

The electrical resistance of a wire, determined by its material, length, and cross-sectional area, affecting the flow of electric current through it.
