As you know, a capacitor has two terminals, and we measure capacitors in terms of capacitance. Capacitance (C) is the ability of a capacitor to store energy. The unit of capacitance is Farad. Let’s see some fundamental mathematics of capacitance. You can see that capacitance is the ratio of total charge and the voltage.

There are several techniques used to measure capacitance, and each has its own advantages and limitations. Some common methods include: Bridge method: This method involves connecting the capacitor in a bridge circuit and measuring the voltage across the capacitor. The voltage is proportional to the capacitance, allowing us to calculate its value.
Let’s get into the practical method of capacitance measurements. You may encounter two cases in which you may measure the capacitor. The first case would be a solo capacitor. No matter what is the situation the first step is to discharge the capacitor fully. A capacitor is a charge storing device.
Several circuit architectures for capacitance measurements have been proposed, where only a few of them consider lossy capacitances , . In the authors classify capacitance measurement circuits to mainly four categories, which are resonance methods, oscillation methods, charge/discharge methods, and AC bridge methods.
The only practical way to measure capacitance without a multimeter or capacitance meter is by noting the written value on the capacitor body. Which we covered in the above section. The rest of the methods is my try to share the knowledge that without a capacitance meter what are the other possible solutions?
Note: Testing a capacitor in the capacitance mode can only be performed if the analog or digital multimeter has the farad “Farad” of Capacitance “C” features. The function of capacitance mode in a multimeter can also be used to test the tiny capacitors.
