To test a capacitor, you can use an ohmmeter on the multimeter setting. Place the probes across the leads of the capacitor to determine its resistance and ascertain whether the capacitor is good or bad.
Method 1: pointer multimeter measurement. 1, check the electrolytic capacitor with the resistance meter of multimeter. The two lead wires of the electrolytic capacitor can be divided into positive and negative.
Check the capacitor’s voltage rating. This information should be printed on the outside of the capacitor as well. Look for a number followed by a capital “V,” the symbol for “volt.” Charge the capacitor with a known voltage less than, but close to, its rated voltage.
When checking its quality, the resistance of the electrolytic capacitor (6V or l0V) with lower voltage withstand should be placed in R 100 or R 6550 Such electrolytic capacitors are good. The larger the capacity of the electrolytic capacitor, the longer the charging time, the slower the pointer oscillating.
Capacitors are storage devices that store a potential difference of charges across their plates, which are voltages. To test if a capacitor is functioning properly, you can charge it up with a voltage and then read the voltage across the terminals. The anode has a positive voltage and the cathode has a negative voltage.
Disconnect the capacitor from its circuit. Set your multimeter to its resistance setting. This setting may be marked with the word “OHM” (the unit for resistance) or the Greek letter omega (Ω), the abbreviation for ohm. If your unit has an adjustable resistance range, set the range to 1000 ohm = 1K or higher.

In this article, we will go over different tests that we can use to tell whether a capacitor is good or not, all by utilizing the functions of a digital multimeter. There are many checks we can do to see if a capacitor is functioning the way it should.
By following these simple methods—discharging the capacitor, visually inspecting it, using a multimeter, and applying the fuse or incandescent bulb test—users can effectively assess capacitor functionality without the need for advanced …
The capacity of a capacitor does not determine its quality, but rather its storage abilities. The capacitor''s capacity must match the device''s working condition; otherwise, it can lead to circuit malfunction. As for quality, it is determined by materials used, build construction and manufacturer''s quality control.
