How to Test Electric Components with a Multimeter
- Continuity tests measure if electricity can flow through the part.
- Resistance tests how much current is lost as electricity flows through a component or circuit.
- The third common test is for voltage, or the force of the electric pressure.

How do you test resistors and capacitors?
Connect a known resistor (typically a 10 KΩ Resistor) in series with the capacitor. Complete the circuit by connecting a power supply of known voltage. Turn on the power supply and measure the time taken for the capacitor to charge to 63.2\% of the supply voltage.
How do you test a capacitor with a digital multimeter?
Connect the multimeter probes to the leads of the capacitor (red to positive and black to negative in case of polarized capacitors). The Digital Multimeter will show a reading of resistance on the display and soon it will display the resistance of an open circuit (infinity).
How do you check the condition of a capacitor?
The spark from the capacitor can be used to determine the condition of the capacitor. If the spark is large and strong, then the capacitor is in good condition. If the spark is small and weak, you need to replace the capacitor. This method can be used for capacitors with smaller capacitances.
What is the difference between capacitors and resistors?
Resistors are components that limit or hinder the flow of current in the circuit. They are usually color coded devices. Capacitors are components that can store electric charges. They can be used to filter out AC components from a rectified DC supply.
How to identify polarized and non-polished capacitors?
In case of a polarized capacitor, connect the red probe with the positive terminal of the capacitor (generally, the longer lead) and the black probe to the negative terminal. In case of non – polarized capacitor, connect it either way as they do not have polarity.
