Electron charge in accelerating motion will produce _.
Correct answer: C. EM waves
- A. Electric field
- B. Magnetic field
- C. EM waves
- D. None of these
Explanation
Correct Option: CThis option is correct because accelerating charges produce changing electric fields and magnetic fields. Changing electric fields produces magnetic fields and changing magnetic fields produces electric fields. This interplay between the induced electric field and magnetic field leads to propagation of electromagnetic waves

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.
