Mega Ohm

Volt-ampere

Volt-ampere-reactive

Watt

Measure of the opposition to current flow in an electrical circuit

The pressure from an electrical circuit's power source that pushes charged electron

A flow of electrical charge carriers

The amount of energy transferred or converted per unit tim

The current flowing into a node (or a junction) must be equal to the current flowing out of it

The induced voltage in a circuit is proportional to the rate of change over time of the magnetic flux through that circuit

The current through a conductor between two points is directly proportional to the voltage across the two points

The power equals the voltage across a component times the current passing through that component
