8.2: Capacitance and Capacitors
If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …

Understanding Capacitive Voltage Sensors | Fluke
The capacitive voltage sensor works because when you hold the barrel in your hand and place the tip near a live conductor, you are inserting the high impedance sensing element into a capacitively coupled series circuit. As your hand and body form a relatively large capacitor coupled to the floor. The sensor tip is a small capacitor coupled to the live …
Indicating the charge level on a capacitor with an LED
The way you make sure a high voltage capacitor is completely safe before working on it is to have a wire connecting both terminals together. Clip a wire onto both terminals. Use a conventional multimeter, with a HV probe if necessary, to see whether it''s safe to attach the wire.
