A transfer instrument employed in the standardization of a polar type $$a.c$$ potentiometer is ______

For the circuit shown in Fig, the wattmeter reading will be .... W and the power dissipted in the load is ......W

If an induction machine is run at above synchronous speed, it acts as

A single-phase alternator has a synchronous reactance of $$2$$ $$ohms$$ and negligible resistance. If it supplies $$10$$ $$A$$ to a purely capacitive load at $$200V,$$ then generated $$e.m.f$$ will be ... $$V$$ and the regulation will be ...... $$\% $$
