Energy in an inductance coil is stored in the form of:
Correct answer: C. Magnetic energy
- A. Electrical energy
- B. Light energy
- C. Magnetic energy
- D. Heat energy
Explanation
The correct option is **magnetic energy**. In an inductance coil, energy is stored in the form of a magnetic field surrounding the coil. When current flows through the coil, a magnetic field is generated, and this field stores energy. This stored magnetic energy can be released back into the circuit when the current changes, making inductors useful components in circuits for storing and releasing energy.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
