The circuit shown is used to investigate the charge and discharge of a capacitor. The supply has negligible internal resistance. When the switch is moved to position \(2\), electrons move from the ...

Ohmic resistors are generally employed to limit the current when charging capacitors. This, however, is accompanied by technical risks. If, for example, the capacitor short circuits or the relay has a ...

Part 2 goes further into the methods that can help lower EMI in switched-cap designs, including implementation of active EMI filters and visible light communication. Part 2 delves further into why ...
