4.1 Capacitance Measurement

Understanding Capacitance

Capacitance is the ability of a component or circuit to store an electric charge. It is measured in farads (F), with common subunits including microfarads (μF), nanofarads (nF), and picofarads (pF). Capacitors are used in a wide range of applications, from filtering and smoothing signals to energy storage and timing circuits.

How to Measure Capacitance

1. Set the Dial: Turn the dial to the capacitance (F) setting. This is usually indicated by a capacitor symbol (two parallel lines, one curved and one straight).

2. Discharge the Capacitor: Before measuring, ensure the capacitor is fully discharged to avoid damaging the multimeter and obtaining false readings. Use a resistor or a specialized discharge tool to safely discharge the capacitor.

3. Connect the Test Leads: Plug the black test lead into the COM jack and the red test lead into the VΩHz jack.

4. Measure the Capacitance: Place the probes across the capacitor terminals, ensuring proper contact.
