Glossary of Power Terms
Alternating Current (AC): The current that is commonly flowing through
the electrical outlets in your home. It is an electrical current in the form of
a sine wave that oscillates up and down continuously.

a sine wave that oscillates up and down continuously.
Amp: An abbreviation for Ampere. This is a unit of electrical current.
Direct Current (DC): An electrical current flowing in one direction only.
DC current does not have a wave form.
DC current does not have a wave form.
Electromagnetic Interference (EMI): Electrical interference generated by
appliances and many other electrical components that cause degradation
of sound and picture quality in audio and video equipment.

of sound and picture quality in audio and video equipment.
Ground: A conducting object, such as a wire, that is connected to a
position of zero-voltage potential. Common connecting points are ground
rods or cold-water pipes that are connected to the Earth.

rods or cold-water pipes that are connected to the Earth.
Joule Rating: A measure of electrical energy. The higher the joule rating,
the more electrical surges a device can absorb before failing.
the more electrical surges a device can absorb before failing.
Maximum Spike Current: The maximum current (in Amps) that can be
absorbed before failing. The higher the maximum spike current, the more
current a device can absorb without failing.
absorbed before failing. The higher the maximum spike current, the more
current a device can absorb without failing.
Radio Frequency Interference (RFI): Electromagnetic radiation, which
is emitted by electrical circuits carrying rapidly changing signals as a by-
product of their normal operation, and which causes interference or noise
to be induced in other circuits.

Spike: A very fast transient variation in voltage or current. Many small
transients, over time, cause components to wear and fail.

Surge: An increase in voltage or current significantly above the designated
level in a flow of electricity.
