What is the realtionship among voltage current and resistance in a circuit?
Ohm's Law Voltage = Current x Resistance
Calculating x r ratio of distribution transformer?
To calculate X/R, you must know what X and R are, then simply divide. The transformer test report should provide this information, and if not, there are ANSII standard values that can be used as estimates. The X value, or the % impedance are usually given explicitly in the test report (sometimes both, but not always). The R value may be given as load loss at the base MVA rating. To find % R, take the load loss (in watts or kilowatts), and divide by the base MVA. The % impedance is = %R + j%X, so you may need to do some (vector) math to get %X if not explicitly given.
How do you write a C-program to find range of a set of numbers?
#include<stdio.h> #include<conio.h> void main() { int x[10],r; for(int i=1;i<=5;i++) { printf("enter the number"); scanf("%d",&x[i]); } r=x[5]-x[1]; printf("%d",r); getch(); }
When using Ohms law to determine voltage what formula would be used?
........V I = ------ ........R I = Ohm's Law V = Voltage R = Resistance (Ignore the dots they stop V and R from moving to the left!)
Write a c program to convert from cartesian to polar coordinates?
the equation that convert from cartesian to polar coordinates and vice versa r = sqrt (x*x+y*y); phi = atan2 (y, x); x = r*cos (phi); y = r*sin (phi);
