Electrical Engineering XYZ MCQ on The dielectric used in variable capacitor is generally with explanation and video illustration of variable capacitors.
The dielectric used in variable capacitor is generally:
- Air
- Electrolyte
- Solid
- None of these
Correct answer: 1. Air
Variable Capacitors are the capacitors whose capacitance may be intentionally and repeatedly changed mechanically or electronically. The figure below displays a mechanical variable capacitor that has two parts, rotor and stator.
You can rotate the rotor in order to change output capacitance of capacitor.
The ElectricalEngineeringXYZ short below illustrates the working of variable capacitor:
