Figure (PageIndex{2}): (a) Capacitors in parallel. Each is connected directly to the voltage source just as if it were all alone, and so the total capacitance in parallel is just the sum of the individual capacitances. (b) The equivalent capacitor has a larger plate area and can therefore hold more charge than the individual capacitors.
Depending on the sophistication of the meter, it may display the capacitance only, or it may also measure a number of other parameters such as leakage, equivalent series resistance (ESR), and inductance. For most purposes and in most cases the capacitor must be disconnected from circuit; ESR can usually be measured in circuit.
Capacitors are the energy reservoirs that supply bursts of power to maintain consistent operation during transient demands. To accurately measure capacitors, we use capacitance meters.

A capacitor can be tested for its functionality directly by entering the capacitance mode in the multimeter and performing the following steps: Remove the capacitor to be tested from the electric board. Discharge the capacitor completely by connecting it across a resistor, and remove the capacitor thereafter for testing.
Capacitance meters carry measurement parameters Cp-D, Cp-Q, Cp-Rp, Cp-G, Cs-D, Cs-Q and Cs-Rs. Cp equals the capacitance value measured with the parallel equivalent circuit model. Cs is the capacitance value measured with the series equivalent circuit model.
Connect the capacitor terminals to the leads of the probe (positive terminal of the capacitor to the red probe and the negative terminal of the capacitor to the black probe of the multimeter). In a typical polar capacitor, the longer lead is the positive terminal, and the shorter lead is the negative terminal.
Connect the capacitor leads to the probes of the multimeter (positive terminal to the red and negative terminal to the black probe, respectively). Shift the knob of the multimeter, and choose the DC voltage range.
