Capacitor
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone is a passive electronic component with two terminals.
Fixed vs Variable Capacitors: What''s the Difference?
As the name would suggest, fixed capacitors have a fixed capacitance. This means that the capacity of the device to hold an electric charge will remain at the same value and cannot be adjusted. Of the two types, fixed capacitors are the most common and have far more applications than variable capacitors.
