Alternating Currents (AC) Mcq Viva interview Short questions answers

 1. The a.c. system is preferred to d.c. system because - a.c. voltage is easily changed in magnitude

2.  In a a.c. system, we generate sine wave from because - it produces least disturbance in electrical circuits.

3. Friction-will produce A.C. voltage.

4. Electroplating - will work only D.C. voltages.

5. In a D.C circuit we consider the resistances (R) only. But in an A.C circuit in addition to resistance (R), inductance (L), and capacitance (C).
