What does a microfarad measure in relation to condensers?

A microfarad is a unit of measurement that quantifies the capacitance of a condenser, which is another term for a capacitor. Capacitance refers to the ability of a device to store an electric charge. When capacitance is measured in farads, microfarads (µF) represent one-millionth of a farad, making it a scale that is useful for measuring smaller capacitance values commonly found in electronic components.

Capacitance indicates how much electrical energy can be stored in a capacitor for a given voltage across its plates. A higher capacitance value means that the capacitor can store more charge. Therefore, the correct answer signifies the role of microfarads as a measure of the capacity of a condenser to hold electrical energy, rather than measuring voltage, current, or resistance.
