Assume that each diode as shown in the tịgure has a forvard bias resistance of \(50 \Omega\) and an infinite reverse bias resistance. The current through the resistance \(150 \Omega\) is
- A \(0.66 \mathrm{A}\)
- B \(0.05 \mathrm{A}\)
- C zero
- D \(0.04 \mathrm{A}\)
Answer & Solution
Correct Answer
(D) \(0.04 \mathrm{A}\)
Step-by-step Solution
Detailed explanation
The circuit is As the lower diode attached to \(100 \Omega\) resistance is in reversed biased so, \(1 t\) is non-conducting Now, the circuit can be redrawn as, \(\therefore\) Current through the circuit, \(I=\frac{V}{R}\) \[ =\frac{10}{250}=0.04 \mathrm{A} \]
