What describes the ability to store energy in a magnetic field?
- A.Admittance
- B.Capacitance
- C.Resistance
- D.Inductance (correct answer)
WhyInductance describes the ability to store energy in a magnetic field. Inductance is the property that describes storing energy in a magnetic field, created around a conductor, often a coil, as current flows through it, answer D. Admittance (A) describes how easily AC current flows through a circuit, capacitance (B) stores energy in an electric field instead, and resistance (C) dissipates energy rather than storing it.
