Familarization of electronic component – Capacitor

Objective:

How to measure the capacitance value of various colour coded carbon capacitor.

Theory:

ELECTROLYTIC CAPACITOR: – It is polarized capacitor whose anode (+) is made of a particular metal on which an insulating oxide layer forms by anodization, acting as dielectric. Its plates achieve a large capacitance/unit volume.

NON-ELECTROLYTIC CAPACITOR: It is non-polarised fixed capacitor. It purely depends on the dielectric constant of bulk capacitor, whose capacity is two electrodes separated by the dielectric plates.

There are different types of capacitor such as ceramic capacitor, polyester capacitor, disc type capacitor, film capacitor, paper capacitor, air gap capacitor, glass capacitor, mica capacitor etc.

Conclusion:

We can get difference value of capacitor from difference type of capacitor. We are neglected instrumentation error.
