List of top Physics Questions on applications of diode asked in VITEEE

In a common emitter transistor, \( \beta = 100 \), \( R_c = 2\,\text{k}\Omega \), and the output voltage is \(2\,\text{V}\). If \( R_b = 1\,\text{k}\Omega \), find the input voltage.

The V-I characteristic of a diode is shown in the figure. The ratio of forward to reverse bias resistance is:
