Capacitors come in a variety of shapes and sizes, so you must determine what type of capacitor you are testing. The two most common types are electrolytic capacitors and ceramic capacitors. Electrolytic capacitors have an anode and cathode, while ceramic capacitors typically only have two leads that connect to the circuit board.
Tools Required for Capacitor Testing. To test capacitors effectively, you will need the following tools:. 1. Klein Multimeter: A versatile multimeter with capacitance measurement capability. 2. Capacitor Discharge Tool: Used to safely discharge capacitors before handling. 3. Resistor: A 1kΩ resistor for testing electrolytic capacitors.
Connect the leads to the capacitor''s terminals. Note that electrolytic capacitors (most commonly shaped like cans) are polarized, so identify the positive and negative terminals before you connect the multimeter''s leads. This may not matter much for your test, but you''ll certainly need to know this before using the capacitor in a circuit.
