On what does the capacitance of a capacitor depend?

What Does Capacitance Depend On? The capacitance (C) of a capacitor depends on several main factors: Plate Area (A): The capacitance increases with the area of the plates. Larger plates can hold more charge. Mathematically, this is expressed as C∝A. Plate Separation (d): The capacitance decreases as

Why is it that when an inductor produces high voltage and not a high current?

When an inductor collapses (for example, when a switch in the inductor circuit suddenly opens), it produces a high voltage rather than a high current. This can be explained by the basic properties of an inductor and its energy storage mechanism. Here is a detailed explanation: Basic Properties of an
