Now let's go back to AC circuits, and combine an inductor, a resistor, and a capacitor all in one circuit. Each component will behave differently when connected to the source of alternating voltage.

Capacitor C1 removes ripples from AC so that low voltage DC is available to power the LEDs. Cx is the X rated AC capacitor that reduces AC voltage through capacitive rectance property. Resistor R1 is ...

The circuit in Figure 1 provides a low-cost, isolated ac-line monitor that measures ac-line-voltage level and has some other unique capabilities. The analysis of the circuit is straightforward: When ...
