Amps = Watts ÷ Volts

Volts = Watts ÷ Amps

Negative (-) charged electrons
move through the wire toward
the positive (+) terminal of the
source of electricity, the current is indicated in the
picture as going from positive
to negative

Ben Franklin originally named
charges positive (+) and negative (-) when he was studying static electricity. Later, when scientists were experimenting with electrical currents, their conclusion was electricity travels from (+) to (-), and that became the convention.

This was before electrons were discovered. We now know the negative charged electrons move toward the positive, which is the opposite direction that people show current moving. It is confusing, once a convention is made, not easily corrected.
