Thanks, guys. I'm definitely impressed with myself that I was able to get my brain to figure that out, as simple as it was. However, you lost me with the zener diode. I completely understand the concept that the voltage may vary with load on the pump, however, I have no idea how I would...

The power supply reads that it is rated for DC output 120W or 6.32A.

Hi. I'm hoping someone can help me out with a pretty simple physics question. My electrical circuit skills are pretty rusty, so please bear with me. I'm using a 19V DC laptop adapter to power a 12V DC pump motor. The pump is rated for 3.5A. I have an on/off switch between the power supply...
