Capacitance Definition

Another important property in AC electronic circuits, besides resistance and inductance, is capacitance. Capacitance is measured in units. The unit of capacitance is the farad. While inductance is represented in a circuit by a coil, capacitance is represented by a capacitor. In its most basic form,

Lenz's Law Explained

Lenz's Law, named after the Russian physicist Heinrich Lenz (1804-1865), is a fundamental principle in electromagnetism. It states that the direction of the induced electromotive force (emf) in a closed conducting loop always opposes the change in magnetic flux that caused it. This means that the in

What is Inductance?

What is Inductance? Inductance occurs when a change in current flow is exploited for the purpose of preventing signals with a higher frequency component from passing while allowing signals of lower frequency components to pass. This is why inductors are sometimes referred to as "chokes," since they
