BASIC CONCEPT OF ELECTRICITY
low of electricity through
an object, such as a wire. It is
measured in amps (A); if the current is
very small then it is described in milliamps (mA), 1000 mA = 1A.
The driving force
(electrical pressure) behind the flow of
a current that is measured in volts (V).
BASIC CONCEPT OF ELECTRICITY
The property of a
material that limits current flow is
known as its resistance. It can be
measured in ohm (Ω).
