Consider a circuit consisting of a capacitor (\(20\ \mu\)F), resistor (\(100\ \Omega\)) and two identical diodes as shown in figure. The resistance of diode under forward biasing condition is \(10\ \Omega\). The time constant of the circuit is \(\alpha \times 10^{-3}\) s. The value of \(\alpha\) is _____
- A \(2.2\)
- B \(2.0\)
- C \(2.1\)
- D \(2.4\)
Answer & Solution
Correct Answer
(A) \(2.2\)
Step-by-step Solution
Detailed explanation
From the given circuit diagram, the battery is connected such that its positive terminal is upwards. This means the current will flow in the clockwise direction during the charging of the capacitor. In the parallel combination of the two diodes, the left diode is pointing…
