Sub Topic Name : Logic Gates-And Gate
Introduction

AND gate can have more than one input and produces one output.

Pre-Requisites:

Introduction about digital signals, Basic functions of logic gates

Activity:

In your physics lab just form an AND gate with the help of teacher and find the output of the gate.

Real Life Question:

“When it gives the output ‘1’?” “What is the commonly used symbol for AND gate?”

Gadgets How it can be used
Real life uses :

Many devices such as, Radio, Transistor, television, amplifiers, computers, watches etc.

Places to visit :

Your physics lab, where you can see the diagram representation of the AND gate.

Practical examples around us
Examples Explainations
All the electronic devices AND gate is used in many electronic devices as the basic unit of the construction.
What you learn in Theory:

This gate has two or more than two inputs. AND gate produces output ‘1’ when both the inputs are ‘1’. AND gate produces output ‘0’ when any of the input is ‘0’.

What you learn in Practice:

Electronic devices in daily practice use the digital system of signals having number of AND gates i.e. they have only two inputs ON or OFF.
