Question

Assume that each diode shown in the figure has a forward bias resistance of 50 Ω and an infinite reverse bias resistance. The current through the resistance 150 Ω is

(a) 0.66 A

(b) 0.05 A

(c) zero

(d) 0.04 A

Answer 1

The correct option is (d) 0.04 A.

Explanation:

In the circuit, diode D₁ is reverse biased and offers infinite resistance, diode D₂ is forward biased and offers 50 Ω  resistance. The equivalent circuit is shown in the figure.
