I'm having issues with this simple circuit. If you look in the top left corner of the image attached, I have a dremel tool powering an 18vdc motor which puts out current at 1.96 amps. Then it goes to a switch. The wires then go to an 8 ohm resistor(white rectangle) then to a 4700μF capacitor(blue cylinder). Now where the pencil is in the picture, I still have 18 volts being regulated by the capacitor. Where I have soldered the ground wire from the switch and the hotwire to the capacitor I still get 18 volts. There is a connector at the end of the black wire at the bottom right that plugs into a universal powermat, and I cannot get 18 v out of the end to power the mat. Can anyone help me?
