capacitor

$begingroup$ a cap dropper isn''t a good match as unlike an LED, the fan uses different amounts of power at different times and temps; primarily - a lot when you first turn it on. A diode should half the speed, or stop it completely depending on the type of motor. A resistor would be a better way of slowing it down than a cap, a triac phase angle control even better, …

Transistor Capacitor Circuit

If we use a 47 kiloohm resistor we see it is very slow. If we use a 1 kiloohm resistor it flashes very, very fast. So the larger the resistor the slower the flashing. I''m going to use a 22 kiloohm resistor and a 100 microfard capacitor, because I think this works well and it looks very nice- and also, the capacitor is physically quite small.

21.6: DC Circuits Containing Resistors and Capacitors

RC Circuits. An (RC) circuit is one containing a resisto r (R) and capacitor (C). The capacitor is an electrical component that stores electric charge. Figure shows a simple (RC) circuit that employs a DC (direct current) voltage source. The capacitor is initially uncharged. As soon as the switch is closed, current flows to and from the initially uncharged capacitor.

I want to control motor speed with capacitors

If a small induction motor has a non-linear load, such as a fan, you can somewhat control the motor speed by reducing the motor voltage. In that case the motor no longer has sufficient torque to maintain its speed and starts operating at a lower speed, with a large amount of slip between the synchronous speed and the actual speed.
