In what scenario is a capacitance checker most commonly utilized?

A capacitance checker is primarily utilized to measure the capacitance of capacitors. This instrument is specifically designed to determine how much electrical energy a capacitor can store, which is crucial for ensuring that capacitors in circuits are functioning correctly and within their specified ratings. By providing an accurate measurement of capacitance, technicians can assess whether a capacitor is operating properly, whether it has degraded over time, or if it needs replacing.

While checking continuity involves ensuring that electrical pathways are intact, measuring inductance pertains to inductors rather than capacitors, and testing resistance levels is related to resistors, none of these tasks fall under the primary function of a capacitance checker. Thus, the tool's primary use and purpose are to measure the capacitance of capacitors accurately, making the correct option the most contextually relevant choice.
