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.

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.

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.

components that cause degradation 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.

Joule Rating:
a measure of electrical energy. The higher the joule rating, the more
electrical surges a device can absorb before failing.
a measure of electrical energy. The higher the joule rating, 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.
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.
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.
