WAP to find factorial of a given number

 using System;

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace factorial
{
Class Program
{
static void main(string[] args)
{ int fact = 1, i, n;
Console.WriteLine("Input any number.");
n = Convert.Toint32(Console.ReadLine());
if( n == 0)
{
Console.WriteLine("The factorial of 0 is 1.");
Console.ReadLine();
}
else 
{
for(i=1; i<=n; i++)
{
fact = fact*i;
}
Console.WriteLine("The factorial of a given number is: {0}", fact);
Console.ReadLine();
}
}
}
}


OUTPUT:
Input any number. 
5
The factorial of a given number is: 120

Physical variables and transducer

unit 3 Physical Variables and transducers  Sensor Sensors are electrical devices that have the capability of sensing different physical variables. The sensor may be classified on different bases one of them is a physical quantity. Hence on the basis of a physical quantity or physical vibration involved the sensors are classified as: Resistive sensor  The input being measured is transformed into a change in resistance. examples: potentiometer, resistance thermometer, strain gauge, etc. Inductive sensor The input being measured is transformed into a change in resistance. example LVDT. Capacitive Sensor The input being measured is transformed into a change in capacitance. example: capacitive Displacement sensor. On the basis of power supply required: Active Sensor Active sensors are those which do not require an external power supply.  example: thermo-couple Passive Sensor Passive Sensors are those which require a power supply. example: Potentiometer. Physical variables and their types Th
