Unit for measuring electrical power.
A voltage ripple is a small alternating current on top
of a direct current, which results in a DC voltage that
is not entirely smooth but ripples slightly.
While a battery delivers pure direct current without
any ripple, this is not always the case with a battery
charger. In an old-fashioned battery charger,
50 % of the voltage will contain ripples.
A large voltage ripple shortens the lifespan of a
battery, which needs to be charged with direct
(not alternating) current. In addition, a voltage
ripple can interfere with onboard audio, navigation
and communications systems. Mastervolt battery
chargers supply a flat DC voltage with no more than
0.3 % of ripple voltage.
Unit that measures the rate of energy,
calculated by multiplying volts by amps.
Measure of electrical power in time. One watt-hour
of electricity is equal to one watt of power consumed
over one hour. A 10-watt light bulb uses 10 watt-
hours of electricity in one hour (see also kWh).
