Capacitor''s discharge in AC circuits (Diagram 1). In this figure, Vt is the AC voltage source, which depends on time, while (V_{max} cdot sin(omega t)) is the function defining its sinusoidal behaviour. Because the voltage value of the AC source is decreasing after a=π/2, the capacitor''s voltage will decrease as well.

The top capacitor has no dielectric between its plates. The bottom capacitor has a dielectric between its plates.

Thus, for the same charge, a capacitor stores less energy when it contains a ...
Small capacitors can be discharged directly with a short circuit. Still, where there is a safety issue, larger values might need a discharge (bleed) resistor to control the current value during discharge. Some circuits have high-value ''bleed'' resistors permanently connected across a capacitor to ensure a controlled discharge. This applies ...

I found the transistor at the link below, but it doesn''t look like it has 3 prongs.. uld be a bad camera angle.
This potential difference is accessible when the capacitor is connected to another circuit element. Discharge: If a path is available for the charges to move (for instance, by connecting a resistor across the capacitor), the capacitor starts discharging. The discharge process results in a current flowing in the circuit.
In a cardiac emergency, a portable electronic device known as an automated external defibrillator (AED) can be a lifesaver.

A heart attack can arise from the onset of fast, irregular beating of the heart—called cardiac or ...
