Alternating Current (AC) Alternating Current (AC) An electric current Alternating Current (AC) Alternating Current (AC) Alternating Current (AC)
that reverses direction at regular intervals.
Sources of alternating current are shore
power, generator power, inverter power or
household current.
Ampere (Amp, A) The unit of measure of Ampere (Amp, A) Ampere (Amp, A)

measure for a battery's electrical storage
capacity, obtained by multiplying the current in
amperes by the time in hours of discharge
(Example: a battery which delivers 5 amperes
for 20 hours delivers 5 amperes times 20
hours, or 100 Amp-Hr. o f c a p a c i t y. )

Ampere-Hour Capacity Ampere-Hour Capacity
charged battery to deliver a specified quantity
of electricity (Amp-Hr. , AH) at a given rate
(Amp, A) over a definite period of time (Hr. ) .
The capacity of a battery depends upon a
number of factors such as: active material,
weight, density, adhesion to grid, number,
design and dimensions of plates, plate spacing
design of separators, specific gravity and

Circuit (Parallel) Circuit (Parallel)
Circuit (Parallel) Circuit (Parallel) A circuit which provides Circuit (Parallel)
more than one path for current flow. A p a r a l l e l
arrangement of batteries (of like voltage and
capacity) would have all positive terminals
connected to a conductor and all negative
terminals connected to another conductor. I f

Current Current Current T h e r a t e o f f l o w o f e l e c t r i c i t y o r t h e Current Current
movement rate of electrons along a conductor.
It is comparable to the flow of a stream of
water. The unit of measure for current is
ampere.
Cycle Cycle Cycle I n a b a t t e r y, one discharge plus one Cycle Cycle
recharge equals one cycle.
Direct Current Direct Current Direct Current (DC) Current that flows Direct Current Direct Current
continuously in one direction such as that from
batteries, photovoltaics, alternators, chargers
and DC generators.
