Control the SPEED of direct current??? Other than using wire of
different velocity factor or doping the conductor, I cannot think of
many ways you can do this! You can certainly make the motor
speed change (what's new with that idea?? PWM has been around
for half a century or more...), but ya'll ain't gonna do much about
the speed of electrons in a wire to any meaningful degree. And why
would you want to?? Electrons seem to work just fine at the speeds
they achieve in wire - so why not just leave them alone?
