In a bridge type full-wave rectifier, if Vm is the peak voltage across the secondary coil of the transformer, the maximum voltage coming across each reverse biased diode is:

Correct answer: C. 2Vm

  • A. Vm
  • B. Vm/√2
  • C. 2Vm
  • D. Vm3

Explanation

A full-wave rectifier is defined as a rectifier that converts the complete cycle of alternating current into pulsating direct current (DC). If Vm is the peak voltage across the secondary transformer, the maximum voltage coming across the reverse-biased diode is 2Vm.

About Alternating Current

Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
