Details Base Unit - Farad
Typically measured in micro-farads Symbol: F (1/1,000,000th of a Farad) Also can be in pico-Farads (1/1,000,000,000,000) of a
Farad Also have a working voltage rating
WVDC Similar to resistor power rating
Capacitors are not heat sensitive

How a Capacitor Works A capacitor is two conductors
(plates) separated by an insulator (dielectric)
A capacitor stores energy when it is connected to a voltage source (such as a battery).
Current flows until the capacitor becomes charged to the same voltage as the source.

Discharging a Capacitor
Capacitor has the ability to discharge immediately
Battery discharges over time Short leads of capacitors before working with
them Use a resistor to slowly discharge a capacitor so
it is not damaged Danger of Electrical Shock
