If a centre tap transformer is used with two p-n junction diodes for full wave rectification then output voltage of rectifier with respect to each diode is (secondary voltage of transformer =V_s )

Options

  1. A2 ~V _ s
  2. B( 2 3 ) V_s
  3. C( 1 2 ) V_s
  4. D( 3 2 ) V_s

Correct answer

C. ( 1 2 ) V_s

Step-by-step solution

A center-tap full-wave rectifier employs a transformer with a center-tapped secondary winding where the total voltage V_s is equally divided, yielding V_s 2 from center tap to each end. Each diode rectifies the voltage across its respective half-winding, producing an output voltage of V_s 2 for each. Final Answer: C
