CAPACITOR

Capacitor “OR” Condenser “OR” Filter

Capacitor is an electronic component that stores electric charge. The capacitor is made of 2 close conductors (usually plates) that are separated by a dielectric material. The plates accumulate electric charge when connected to power source. One plate accumulates positive charge and the other plate accumulates negative charge.

Electrical or electronic device that (like a battery) stores electric current for releasing it at a specific time or rate but (unlike a battery) does not generate it. Also called condenser.

Capacitors are components that are used to store an electrical charge and are used in timer circuits. A capacitor may be used with a resistor to produce a timer. Sometimes capacitors are used to smooth a current in a circuit as they can prevent false triggering of other components such as relays. When power is supplied to a circuit that includes a capacitor - the capacitor charges up. When power is turned off the capacitor discharges its electrical charge slowly.

The capacitance is measured in units of Farad (usually in microfarad [μF]).

Farad

Farad is the unit of capacitance. It is named after Michael Faraday.

The farad measures how much electric charge is accumulated on the capacitor.

There are four types of Capacitor

1. Normal Polar Capacitor
2. Normal Non-Polar Capacitor
3. Micro Polar Capacitor
4. Micro Non-Polar Capacitor

1. Normal Polar Capacitor

Symbol

Checking

Meter Set X10 and Capacitor Discharge.Meter Positive Probe Connect on Capacitor Positive Leg and Meter Negative Probe Connect on Capacitor Nagative Leg.Meter Show Reading and back Zero Reading Capacitor it's ok.

2. Normal Non-Polar Capacitor

This is used in both directions.

Symbol

Checking

Analog Meter is set x10 then Non Polar Capacitor doesn’t Reading on Meter its ok.

3. Micro Polar Capacitor

Checking

A good indication for MICRO POLAR CAPACITOR  shows the meter needle deflecting towards zero it's OK.

4. Micro Non-Polar Capacitor

Checking

A defective indication for an MICRO NON-POLAR CAPACITOR  shows that the meter will rest on zero it's OK.
