The document describes a program written in C for solving DC networks using mesh analysis, where it prompts the user to input a resistance value to calculate current for specific branch configurations. It includes two distinct programs for different resistance variables and their respective formulas to compute current. The code utilizes standard libraries and functions for input/output operations in console applications.

2. The Problem
• Write a program to solve this network that will
ask input for ‘a’ and find current, with:
b=6 , c=6 , d=4 , e=6 , f=100 , g=50.

3. The Program
• #include<stdio.h>
• #include<conio.h>
• #include<math.h>
• void main()
• {
• //using mesh analysis//
• float a,i2;
• clrscr( );
• printf("Enter the value of resistance:");
• scanf("%d",&a);
• i2=-(1590+50a)/(216+36a);
• printf("The current through 6 ohm branch is=%d",i2);
• getch();
• }

4. The Problem
• Write a program to solve this network that will
ask input for ‘c’ and find current, with:
b=6 , a=4 , d=4 , e=6 , f=100 , g=50.

5. The Program
• #include<iostream.h>
• #include<conio.h>
• Void main()
• {
• Float a,b,c;
• Cout<<”enter the value of resistance:”;
• Cin>>c;
• b=500/((6*a)+21);
• a=(25*(6+c))/((18*c)+63);
• cout<<”the current in the 6 ohm branch is “<<b-c;
• getch();
• }
