Which term describes the ability to store electrical energy in the electric field between two conductors?

• A. Capacitance
• B. Inductance
• C. Effective Value
• D. Peak Voltage

Answer: (A)

Storing electrical energy in the electric field between two conductors is described by capacitance. A capacitor holds charge on its plates when a voltage is applied, creating an electric field between the plates. The energy stored is (1/2) C V^2, where C is the capacitance and V is the voltage. Capacitance, measured in farads, represents how much charge per volt the device can store (C = Q/V). This concept is distinct from inductance, which stores energy in a magnetic field around conductors due to current; RMS value relates to the effective AC voltage level, not energy storage; and peak voltage is just the maximum instantaneous voltage, not the amount of energy stored.
