Electrical Terms

Voltage	Electrical potential or a measure of the strength of an electrical source. The unit for voltage is volts.
Amperage	The amount of current flow in a circuit
Current	The flow of electric charge
Resistance	A measure of the degree to which an object opposes the passage of an electric current. The SI unit of electrical resistance is the ohm.
Transformer	An electrical device that transfers energy from one electrical circuit to another by magnetic coupling but without any moving parts. When a different number of turns is used in each coil the current voltage and amperage is changed
Magneto	An electrical generator that has been tuned to create a periodic high-voltage pulse rather than continuous current
Induction	Transfer of electrical energy without direct contact
Electromagnetism	Magnetic field established by current flowing through a conductor
Ohm’s Law	E=IR Voltage = amperage x resistance
