Ampere (A) — Electric current is measured in Amperes, named after André-Marie Ampère.

Capacitor — Capacitors store electrical energy in an electric field.

Alternating Current — AC stands for Alternating Current, where the current periodically reverses direction.

To change the voltage of an AC supply — Transformers are used to increase or decrease the voltage of an AC supply.

Resistor — A resistor is a passive component that only dissipates power and does not amplify or switch signals.
