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);
How do you calculate the dimensions of a rectangle based on a specific ratio if you know its area?
Known Ratio gives: X/Y = R Known Area gives: X*Y = A R and A are known. Two equations. Two unknowns. X = R*Y R*Y*Y = A Y^2 = A/R Y = SQRT(A/R) X = R*SQRT(A/R)
What is the ratio of two odd functions?
What is the ratio of two odd functions? Ans: f, g are odd func on the same domain D. Let r = f / g, assuming g non zero everywhere on D. r(-x) = f(-x) / g(-x) = -f(x) / [-g)(x)] = f(x) / g(x) = r(x), and so r is an even function.
How do you find a number of somthing from a ratio?
If you are given a ratio, r , then r = x/y ( If the ratio is given as x : y, or x to y think of it as x/y . Also remember the r% means r/100 if the ratio is given as a percentage. ) Therefore by basic algebra, x = ry and y = x/r . So you find either number from the other, given the ration. Example The ratio of boys to girls in a physics class is 8 to 2. There are 4 girls. How many boys are in the class? b/g = 8/2 so b/4 = 8/2 and b = 4(8/2) = 16 boys in the class.
How do you find the radius of a sphere that has a ratio of 1 to 2 for volume and surface area?
Surface area of sphere is 4 x pi x r x r Volume of sphere is (4/3) x pi x r x r x r Hence ((4/3) x pi x r x r x r) / (4 x pi x r x r) = 1/2 ((4/3) x r) / (4) = 1/2 (1/3) x r = 1/2 r = 1 and 1/2
What is the ratio of the volumes of a sphere and a cone with the base diameter and the altitude of the cone equal to the diameter of the sphere?
The ratio is given as the sphere volume divided by the volume of the cone. The volume of a sphere that satisfies these conditions is 4/3 x pi x r cubed, and the volume for the cone is 2/3 x pi x r cubed, where r is the radius and pi is equal to 3.14. Dividing these two volumes, you find the resulting ratio is 2.
If the ratio between the radii of two spheres is 23 then what is the ratio of their volumes?
Volume of a sphere of radius r: V = 4pi/3 x r3 If the ratio of the radii of two spheres is 23,then the ratio of their volumes will be 233 = 1,2167
How do you find the common ratio in a geometric progression when the sum of the first 20 terms is 244 times the sum of its first 10 terms?
Sum of 10 terms is n(r10-1)/(r-1) where n = 1st term. Sum of 20 is n(r20-1)/(r-1) so ratio is (r20-1)/(r10-1). Let r10 be called x. So the ratio is (x2-1)/(x-1) which is just x+1, so x=243. The common ratio is therefore the 10th root of this. Which is square root of 3.
Is there any effect on fault level if generator short circuit ratio is high or low?
Probably... What ratio? X/R? X0/X1? X0/R0? Xd /Xd''? etc.
SIMPLE explanation of the golden ratio?
Two quantities are in a Golden Ratio if the ratio of the bigger quantity to the smaller quantity is the same as the ratio of the sum of the two quantities to the bigger quantity. In algebraic form, if the two quantities are x and y, and x is the bigger of the two, then they are in the Golden Ratio if x/y = (x+y)/x and that ratio is the Golden Ratio. which equals (1 + √5)/2.
Determine the ratio of the volume of a cube to that of a sphere which will exactly fit inside the cube?
let edge of the cube be {x} radius of the sphere inside the cube= x/2 volume of the cube=x^3 volume the sphere=4pi/3*r^3 =4/3*22/7*r^3/8 ratio of the volume=x^3/11x^3/21 =21/11 ans.= 21:11
What is the realtionship among voltage current and resistance in a circuit?
Ohm's Law Voltage = Current x Resistance
What is the relationship between radius ratio and coordination number in crystal packing?
r+ / r- that is the ratio of radii + charge to -charge gives a ratio this ratio is used to determine the CN the table is given a lot of books
