Correct answer: D. all of these
- A. mechanical energy into electrical energy
- B. electrical energy into mechanical energy
- C. magnetic energy into electrical energy
- D. all of these
Explanation
Alternating current (AC) or voltage undergoes continuous variations in magnitude and regularly reverses its direction of flow. This characteristic is represented by a sinusoidal waveform, where the current or voltage changes smoothly from positive to negative and back again over time.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
