Physics A level revision resource: Introduction to capacitors

Unlike the battery, a capacitor is a circuit component that temporarily stores electrical energy through distributing charged particles on (generally two) plates to create a potential difference. A capacitor can take a shorter time than a battery to charge up and it can release all the energy very quickly.

19.5 Capacitors and Dielectrics

Typically, commercial capacitors have two conducting parts close to one another, but not touching, such as those in Figure 19.12. (Most of the time an insulator is used between the two plates to provide separation—see the discussion on dielectrics below.)

resistors

The capacitor is pre-charged to 5v, and then the power to the rest of the system is turned on. With the charged capacitor connected to the gate of the SCR, the SCR starts conductions, which in turn allows the transistor to conduct and sink the digital input to ground. Over time, the capacitor will discharge through R to the point where the …
