Question

Write a C program that finds voltage drop and power dissipated by a resistance (R) when a current (I) flows through it. Resistance and current values are given as inputs. Create a function that would find the voltage drop, and create another function that would find the power. Use these functions in your program and print the voltage drop and power dissipated on the console. The input and output values are single precision floating-point values. Comment your code.

Answer 1

#include <stdio.h>
#include <math.h>

double voltageDrop(float p, float r)
{ double v;
v=p*r;
v=sqrt(v);
return v;
}
double power(float v, float r)
{ double p;
p=(v*v)/r;
return p;
}

int main()
{
printf("Please enter the input for valtage drop \n");
float P,R,V;
double Vd,Pd;
printf("\n Enter the Registance field value: ");
scanf("%f", &R);
printf("\n Enter the Power field value: ");
scanf("%f",&P);
// find voltage drop

Vd=voltageDrop(P,R);
printf("print the voltage drop %lf", Vd);

// find Power

printf("\n*********For Power measure********\n ");
printf("please enter valtage drop: ");
scanf("%f", &V);


Pd=power(V,R);
printf("\n print powe %lf", Pd);

}
