A generating voltmeter must be designed so that it can have a range from 20 to 200 kV dc. Determine the capacitance of the generating voltmeter, given the indicating meter reads a minimum current of 2µA and maximum current of 25 µA. Correspondingly, determine the value current when the voltmeter indicates 20 kV, and 200kV (Assume the synchronous speed of motor for the generating voltmeter is in the range of 1000 rpm ~ 3000 rpm).
