Question

A full wave rectifier circuit diodes (D₁) and (D₂) is shown in the figure. If input supply voltage V_in = 220 sin (100 πt) volt, then at t = 15 ms.

• D₁ is forward biased, D₂ is reverse biased.

• D₁ is reverse biased, D₂ is forward biased.

• D₁ and D₂ both are forward biased.

• D₁ and D₂ both are reverse biased.

Answer 1

D₁ is reverse biased, D₂ is forward biased.

Explanation:

Given: V_M = 220 sin (100 πt)

t = 15 ms = 0.015 s

V_M = 220 sin (100 πt)

= 220 sin (100 π × 0.015)

= `220 sin ((3pi)/2)`

= −220 V

Hence, diode D₁ is reverse biased and D₂ is forward biased.
