Semiconductor Electronics · p-n junction and diodes

Consider a circuit consisting of a capacitor (20 μ20\ \muF), resistor (100 Ω100\ \Omega) and two identical diodes as shown in figure. The resistance of diode under forward biasing condition is 10 Ω10\ \Omega. The time constant of the circuit is α×10−3\alpha\times10^{-3} s. The value of α\alpha is .
