FIXED CAPACITOR
Fixed capacitor is the capacitor in which capacitor value remains fixed.
In these capacitor capacitance cannot be adjusted. A fixed capacitor is classified according to the type of material used as its dielectric, such as paper, oil, mica, or electrolyte.
These types of capacitors are discussed in earlier post.
VARIABLE
CAPACITOR
As clear
from its name variable capacitor is one where A variable capacitor is
constructed in such manner that its value of capacitance can be varied.
A variable
capacitor is similar to motor having rotor & Stator. It consists of two
sets of metal plates arranged so that the rotor plates move between the stator
plates. Air acts as dielectric in these capacitors. As the position of the
rotor is changed, the capacitance value is likewise changed.
àThis type of capacitor is used for tuning most radio receivers.
Its physical appearance and its symbol are shown in figure below.
Another
capacitor consists of two plates separated by a sheet of mica. A screw
adjustment is used to vary the distance between the plates, thereby changing
the capacitance.
Trimmer

This is a really useful insight into choosing the right capacitor. For anyone looking for the Best Capacitor In India, it’s important to consider product quality, application requirements, efficiency, and long-term reliability rather than choosing only based on price. A good-quality capacitor can make a noticeable difference in the performance and stability of electrical systems. Thanks for sharing these helpful points!
