How do you get the proof for Delta Star transformation in capacitors?
Convert all your capacitances to their equivalent impedance, then use Y-Delta Conversion formulae. Impedances mix and match like resistances. If the resistor version is: (Y to delta) Ra = (R1*R2 + R2*R3 + R3*R1)/R2 Rb = (R1*R2 + R2*R3 + R3*R1)/R3 Rc = (R1*R2 + R2*R3 + R3*R1)/R1 Then the capacitor version looks like: Ca = C1*C3/(C1 + C2 + C3) Cb = C1*C2/(C1 + C2 + C3) Cc = C2*C3/(C1 + C2 + C3)
Write a program to find sum of two complex numbers?

What is capacitor derive an expression for total capacitance when three capacitors are connected in parallel?
capacitance C=C1+C2+C3
What molecule is butyne?
Butyne has 4 carbons and a triple bond. The triple bond can be between C1 and C2, or C2 and C3 so there are 2 different "forms" or isomers of butyne.
Three cannibals and three missionaries must cross a river their boat can only hold two people at a time but each missionary and each cannibal can row the boat find a way to cross the river?
3 Missionaries: M1, M2, M3 3 Cannibals: C1, C2, C3 Start Shore A Other Shore B 1. C1, M1 take the boat and cross the river and C1 stays on shore B, M1 comes back to shore A. 2. C2, C3 take the boat and cross the river and C2 stays on shore B, C3 comes back to shore A ( C1, C2 on Shore B). 3. M1, M2 take the boat and cross the river and M1 stays on shore B, M2,C2 come back to shore A (M1, C1 on shore B). 4. M2, M3 take the boat and cross the river and M2, M3 stays on shore B, C1 comes back to shore A (M1, M2, M3 on shore B). 5. C1, C2 take the boat and cross the river and C1 gets off and C2 goes back to shore A and brings C3. All lived happily ever after.
What is the common name for cervical vertebrae?
There are only 2 cervical vertebrae that have common names: the atlas and the axis, they act as the pivot that allows you to turn your head.
Write a program to write the sum of two complex number using friend function and overloading constractor?
#include<iostream.h> #include<conio.h> class complex { int r; int i; public: complex() { } complex(int a,int b) { r=a;i=b; } friend complex operator+(complex,complex); friend show(complex); complex operator+(complex c1,complex c2) { complex c3; c3.r=c1.r+c2.r; c3.i=c1.i+c2.i; return(c3); } show(complex c) { cout<<c.r<<"i+"<<c.i<<endl; } void main() { complex a,b,c; clrscr(); a.complex(3,6); b.complex(4,7); c=a+b; show(a); show(b); show(c); getch() }
Formula for capacitance?
Capacitance is defined as the maximum charge stored in a capacitor per unit potential difference. According to this definition, the formula should be : Capacitance = Charge stored / Potential Difference
How can the primacy index of a countrys population be calculated?
The primacy index can be calculated by the following formula: PI = C1/ (C1 + C2 + C3 + C4) * 100 PI = primacy index C1 = amount of people in the biggest city of the country C2 = amount of people in the second city of the country C3 = amount of people on the third city of the country C4 = amount of people in the fourth city of the country So you divide the population of the biggest city of the country by the sum of the four biggest cities in the country and multiply that by 100. If the PI is > or = to 50, then it is a primate city.
What is the condition for linear phase response of FIR filter?
an FIR filter has linear phase characteristic, if coefficient symmetry (or antisymmetry) with respect to h(N/2) applies. ex: h(n)={c0,c1,c2,c3,c4,c5,c6}, then the corresponding FIR filter would have linear response if: c0=c6, c1=c5, c2=c4.
What is the formula for the determinant of a 3 x 3 matrix?
If the matrix is { a1 b1 c1} {a2 b2 c2} {a3 b3 c3} then the determinant is a1b2c3 + b1c2a3 + c1a2b3 - (c1b2a3 + a1c2b3 + b1a2c3)
How do you do an 'or' in Excel formula?
=IF(OR(C1>100,C2>100,C3>100),"Oops!","Looks Good")Syntax is: OR(condition1,condition2,...)condition = Something you want to test that can either be TRUE or FALSE. You can have up to 30 conditions.
