                                                                                              [Ans 7.5 V]


                 39.  An alternating voltage is defined as:

                     v = 100 sinθ V
                     0 < θ < π
                     v = 0V
                     π < θ < 2π

                     What is the RMS value of this voltage?

                                                                                              [Ans 50 V]


                 40.  Find the RMS value of the sinusoidal voltage waveform shown in Fig. 3.75.
