This peculiar setup allows [Ben Krasnow] to control an alternating current device using one pin on a microcontroller. He’s experimenting with a power drill and has relocated the trigger circuitry that ...
Moving the position of the slider on this resistor, changes the length of wire in the circuit which changes the resistance. A variable resistor is used in some dimmer switches and volume controls. As ...
Very often when simulating an electrical circuit in SPICE, there is a need for a variable passive element such as a resistor, a capacitor or an inductor. Very often when simulating an electrical ...
