162. In each of the three coils of a three phase generator, an alternating voltage having an r.m.s. value of 220 V is induced. Which of the following values is indicated by the voltmeters?

163. Which of the following equations is valid for a balanced load on a starts circuit with a neutral conductor in a four wire star circuit?

164. The true power drawn by a balanced three-phase consumer for line voltage V and line current I is given by

165. . An electric iron designed for 110 V A.C. supply was rated at 500 W. It was put across a 220 V supply. Assuming that at 110 V it supplied 500 W output, (i.e., no losses) at the new voltage it will supply

166. From the Fig. 5.16 it can be concluded that

167.  A coil is connected across a 200 V, 50 Hz supply and takes a current of 10 A. The loss in the coil is 1000 W. The impedance and resistance of the coil are

168.  In an A.C. circuit (sine wave) with R and L in series
