The plastic jars of the air capacitor represent the parallel conducting plates.
<h3>What is Air capacitor?</h3>
Air capacitor is a type of capacitor that uses air as its dielectric. The simplest air capacitors will contain two conductive plates separated by an air gap.
This capacitor stores and releases electricity in the circuit using;
- air as the electrical source,
- balloon as the insulator and
- the plastic jar as the parallel conducting plates.
Thus, the plastic jars of the air capacitor represent the parallel conducting plates.
