  • A half-wave rectifier conducts when the alternating current is positive, which happens during 180° of the A.C cycle, and blocks current during the other 180 degrees
  • A full-wave rectifier conducts during both 180° periods of an A.C cycle; So you can see, it conducts current for twice the amount of time
  • The full-wave rectifier has twice the efficiency of a half-wave rectifier is, that it utilizes both half-cycles of the input

Pavan and Sravan are two persons. If Pavan works with his actual efficiency and Sravan twice of his actual efficiency then it takes 25 days to complete the work. But If Pavan works twice of his actual efficiency and Sravan with his normal efficiency then the work is completed in 20 days. How many days would it take if Sravan alone works with his actual efficiency (in Days)?
