Re: Lightbulbs and Power Resistors?

op's high wattage, low ohms.

I stand corrected.

to sum it up.

an LED is 20mA
a fan is about 100mA

if you want a FAST voltage reduction some creative thinking is
needed. If you just want to make sure the voltage bleeds off a
resistor will handle that.

next question ?

and be done with it.
