Power Supply

Great work on the power supply.

40W is not a whole lot of power.  What is the total power for both supplies?  (My guess is somewhere in the hundreds of watts).

Power = voltage x Current


Voltage is what we always think of when we think of power, but it's only half of what you need to look for.

Current is the other part and it can be trickier to figure out.  If you think about a wire like a water pipe, voltage is how much water is available to pour through the pipe.  Current is how fast the water pours through the pipe.  A wire is like a water pipe for electrons.

POP question.
If a wire is like a water pipe for electrons and volts are how many electrons are available to pour through the pipe, how could you change the current?
