A Cockcroft-Walton type voltage multiplier has six stages with capacitances, all equivalent to 0.03µF. The supply transformer secondary voltage is in the range of 100 kV - 200 kV at a frequency of 150 Hz ~ 220 Hz. If the load current to be supplied is 6 mA, determine: i. the percentage ripple ii. the regulation ii. the optimum number
