imagine a reservoir full of water; better yet... a water tower.
and imagine the faucet in your kitchen sink connected to that water tower.
that potential difference between the tower and your faucet is like voltage.
that's sort of what voltage indicates in an electrical circuit. amps,
on the other hand, indicate the current - that's like how much of the water
passes by a given point of the pipe that connects tower to faucet in a
particular time (when the faucet is turned on, of course!).except, instead
of measuring the flow of water, current in this case measures the flow
of electrons through a conductive medium. which, in effect is the phenomena
we think of as electricity. |
