The relationship between voltage, current (amps), and power (Watts) is
described by the following equation:
P = V x I
Where P is power (measured in watts), V is voltage
(measured in volts) and I is current (measured in amps).
An easy way to think about the relationship between power,
current and voltage is to think of it like a pipe with water flowing through it.
Power is the total amount of water flowing through the pipe.
Voltage would be the size of that pipe.
Current would be the speed at which the water is flowing through the
pipe. If you have a constant amount
of water flowing through the pipe, then naturally the smaller the pipe, the
faster that water will flow. Likewise,
if you use a small voltage more amps will be required to get the same amount of
power. Too many amps in a home
power system will lead to high energy losses and a greater possibility of
electrical fire.
