A capacitor analyzer is designed to check:

The correct answer relates to the primary function of a capacitor analyzer, which is to measure the capacitance of a capacitor. Capacitance is the ability of a capacitor to store electrical energy in an electric field, and it is a key parameter that determines how a capacitor performs in a circuit.

When using a capacitor analyzer, you can obtain an accurate reading of the capacitance value, which is essential for verifying that the capacitor meets its specified ratings and ensuring it will operate correctly in its intended application. This measurement helps to ensure that the capacitor is suitable for its use in filtering, timing, or energy storage, among other applications.

While other factors related to capacitors, such as resistance, voltage rating, and leakage current, are also important for evaluating the health and performance of a capacitor, the primary capability of a capacitor analyzer is focused on capacitance measurement. Different testing equipment may be used to assess these other parameters, but they are not the main function of a capacitor analyzer.
