In an arc rectifier, the drop in voltage at the cathode is approximately Correct Answer 6 to 7 volts

A mercury-arc rectifier is a type of electrical rectifier used for converting the high voltage or high current alternating current into direct current. In a mercury arc rectifier, the cathode voltage drop is due to the expenditure of energy in liberating electrons from the mercury and the voltage drop at the cathode is approximately 6 to 7 volts.
