VOLT
The volt is the unit measure of electrical
pressure. One volt will, when applied across a resistance of one
ohm,
force one
amp
of
current
to flow through the circuit. If you double the
resistance
in the circuit and still apply one volt across the circuit, the current flow
will be 1/2 amp. If you apply two volts across one ohm the current flow through
the
resistor
will be two amps.
Using the water tower analogy...
Note:
Don't take this to mean that a larger battery will have more voltage. It's just to help you visualize what a difference of potential (voltage) means.
Higher force = higher voltage = higher difference of potential
