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
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.
