What does a capacitor analyzer measure?

• A. The voltage output of a capacitor.
• B. The capacitive resistance of a capacitor.
• C. The charge stored in a capacitor.
• D. The inductance of a capacitor.

Answer: (B)

A capacitor analyzer is primarily designed to assess the capacitive properties of capacitors. This includes measuring the capacitive resistance, also known as reactive impedance. This is crucial because it helps technicians evaluate whether a capacitor is functioning correctly within its specified parameters. The ability to measure the capacitive resistance of a capacitor allows HVAC technicians to diagnose capacitor issues, such as whether a capacitor is underperforming or close to failure. Other measurements, like the voltage output or charge stored in a capacitor, while relevant in some contexts, do not encompass the primary function of a capacitor analyzer. The inductance of a capacitor is also not typically a measurement central to capacitors, as capacitors function through capacitance rather than inductance—this means they store energy in an electric field rather than a magnetic field. Therefore, the focus on the capacitive resistance provides a more comprehensive picture of the capacitor's health and functionality.
