Q. The external - characteristics data of two shunt generators in parallel are given as follows:
Load Current, A: 0 5 10 15 20 25 30
Terminal voltage I, V: 270 263 254 240 222 200 175
Terminal voltage II, V: 280 277 270 263 253 243 228
Calculate the load current and terminal voltage of each machine.
(a) When the generators supply a load resistance of 6 .
(b) When the generators supply a battery of emf 300 V and resistance of 1.5 .
Q. Due to what special property does an emitter amplifier work as a buffer amplifier? The circuit design of the emitter follower is such that it has a high input impedance and
