Electrical current refers to the flow of electric charge in a circuit. It is the movement of electrons through a conductor, such as a wire.
Voltage: Voltage is the force that pushes electrical charges (electrons) through a circuit.
Resistance: Resistance is anything that opposes or restricts the flow of electrical current in a circuit.
Amperage: Amperage, also known as electric current intensity, measures how much electrical charge flows past a given point in one second.
