Glossary
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.
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.
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.
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.
