What describes the ability to store energy in an electric field?
- A.Inductance
- B.Resistance
- C.Frequency
- D.Capacitance (correct answer)
WhyCapacitance describes the ability to store energy in an electric field. Capacitance is the property that describes storing energy in an electric field, typically between two conductive plates separated by an insulator, answer D. Inductance (A) stores energy in a magnetic field instead, resistance (B) dissipates energy rather than storing it, and frequency (C) isn't an energy-storage property at all.
