173. A salient pole synchronous motor is running at no load, its field current is switched off. The motor will (a) come to a stop (b) continue to run at synchronous speed (c) continue to run at a speed slightly less than synchronous speed (d) none of these. 174. In a network the sum of currents entering a node is 5∠60°. The sum of the currents leaving the node is (a) 5 ∠60° (b) 5 ∠– 60° (c) 5 ∠240° (d) 15 A. 175. In a synchronous machine, in case the axis of field flux is in line with the armature flux, the machine is working (a) as synchronous motor (b) as synchronous generator (c) as floating machine (d) the m/c will not work . 176. An ideal voltage source is connected across a variable resistance. The variation of current as a function of resistance is given by (a) A straight line passing through the origin (b) a rectangular hyperbola (c) a parabola (d) it could be anyone of the above.
