1 Amps, Volts and Ohms Units of Electrical Measurement

2 1. Amperes: (Amps) a measure of the number of electrons in an electrical current. 1 Amp= 6,281,000,000,000,000,000 electrons (six quintillion two hundred eighty one quadrillion)

3 Units of Electrical Measurement 2. Voltage: A measure of electrical pressure, force or push on electrons in a circuit.

4 Units of Electrical Measurement Ohms: A measure of the resistance to the flow of electrons in a circuit.

5 Ohm’s law states the mathematical relationship between current, voltage and ohms of resistance.
