Electrons Negatively charged particles that orbit around the center of an atom.
Orbits The paths in which electrons travel around the nucleus of an atom.
Amperes The unit of measurement for the number of electrons flowing past a given
point in a circuit in a specific period of time.
Ohm's Law The formula I = E/R, which relates current (I), voltage (E), and resistance
(R).
Magnetic Field A field developed around a conductor when electrons flow through it.
Relay is an electrical device that uses a small current to control a relatively large
current.
Circuit Protection Devices Devices such as fuses, circuit breakers, and cutout switches that protect
circuits from overloads.
