Embibe Experts Solutions for Chapter: Semiconductor Devices, Exercise 2: Exercise - 2

For given circuit, the potential difference $V_{\mathrm{AB}}$ is,

Zener diode is used,

Zener breakdown will occur if,

Refer to the circuit given below. The output voltage $V_0$ is measured between points $a$ and $b$. Then,

An ac source (sinusoidal source with frequency $50 \mathrm{Hz}$) is connected in series with a rectifying diode, a $100 \mathrm{\Omega }$ resistor, a $1000 \mathrm{\mu F}$ capacitor and a milliammeter. After some time the milliammeter reads zero. The voltage measured across the capacitor with a dc voltmeter is

The fundamental frequency of the output of a bridge rectifier driven by AC mains is,

Which one of the following devices does not respond to the intensity of light incident on it?

In a bipolar junction transistor, select the incorrect statement.
