Magnetic Field
Unit of electric pressure
Volt
the rate at which electricity is transferred (watts)
Power
A device that increases or decreases the voltage of alternating current
Transformers
an electric current that flows in one direction steadily
Direct Current
a field of force surrounding a charged particle
Electric Field
unit of resistance
