Amps, Volts and Ohms
Units of Electrical Measurement
Units of Electrical Measurement
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)
Units of Electrical Measurement
2. Voltage: A measure of electrical pressure, force or push on electrons in a circuit.
Units of Electrical Measurement
• Ohms: A measure of the resistance to the flow of electrons in a circuit.
Ohm’s law
•states the mathematical relationship between current, voltage and ohms of resistance.
