What
is the difference between current and voltage?
Answer:
The difference between current and
voltage is often compared to water travelling through a pipe.
The current measures how much water travels through the pipe. Sometimes you
have a big pipe and sometimes you have a little pipe, but neither matters for
the current - the current simply measures how much water goes through it.
Likewise, "current" means the number of electrons that travel through
a wire.
The voltage is a measure of how hard the water is being pushed through the
pipe. If you've got a huge pump driving water through a pipe, the water is
pushed through hard. If the pump isn't working well, it isn't. Voltage is a
measure of the potential difference between one place and another.
