- 1—Voltage is a measure of electrical energy.
Voltage is a measure of the difference in potential energy.
Voltage is also called 'potential difference' - 2—Electrical Current, I, is the rate of flow of electrical charge
Electric Current is a measure of how many electrons are passing per second
It is measured in Amps
- 3Kirchoff's First LawKirchoff's First Law states that the algebraic sum of currents around a junction is zero.
(The total current flowing into a junction is equal to the total current leaving a junction)
