3.4 REVIEW QUESTIONS

A. Short Answer Type Questions

  1. Explain frequency, time period, instantaneous value, maximum value, and average value for a sinusoidal voltage.
  2. What do you understand by harmonic waves of a non-sinusoidal wave?
  3. Why do we use RMS value instead of average value for an alternating quantity?
  4. Show that for a sinusoidal voltage, RMS value is 0.707 times its maximum value.
  5. What is the value of form factor for a sine wave? What is the significance of the value of form factor for an alternating quantity?
  6. The form factors for different kinds of voltage wave shapes have been calculated as 1.0, 1.11, and 1.15. Is it possible to predict the type of the voltage wave shapes?
  7. What is inductive reactance, capacitive reactance, and impedance ...
