Capacitors, like batteries, have internal resistance, so their output voltage is not an emf unless current is zero. This is difficult to measure in practice so we refer to a capacitor''s voltage rather than its emf. But the source of potential difference in a capacitor is fundamental and it is an emf.

constants, (4T) the capacitor in this RC charging circuit is virtually fully charged and the voltage across the capacitor is now approximately 98% of its maximum value, 0.98Vs. The time period taken for the capacitor to reach this 4T point is known as the Transient Period. After a time of 5T the capacitor is now fully
Capacitors use dielectrics made from all sorts of materials. In transistor radios, the tuning is carried out by a large variable capacitor that has nothing but air between its plates. In most electronic circuits, the capacitors are sealed components with dielectrics made of ceramics such as mica and glass, paper soaked in oil, or plastics such ...
When the capacitor is fully charged, the flashbulb''s "ready" light comes on. When a picture is taken, that capacitor releases its energy quickly. Then, the capacitor begins to charge up again. Since capacitors store their energy as an electric field rather than in chemicals that undergo reactions, they can be recharged over and over again.

If the capacitor reads as having fewer than 10 volts, you don''t need to discharge it. If the capacitor reads anywhere between 10 and 99 volts, discharge it with a screwdriver. If the capacitor reads in the hundreds of volts, the safest way to discharge it is with a discharge tool, rather than a screwdriver.

When you take a picture, the trigger closes briefly, connecting the capacitor to a second transformer. This transformer boosts the 200-volt current from the capacitor up to between 1,000 and 4,000 volts, and passes the high-voltage current onto the metal plate next to the flash tube. The momentary high voltage on the metal plate provides the ...
