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 is the equivalent capacitance in a series circuit of capacitors?
In a series circuit of capacitors, the equivalent capacitance is calculated by adding the reciprocals of the individual capacitances and taking the reciprocal of the sum. The formula is 1/Ceq 1/C1 1/C2 1/C3 ... where Ceq is the equivalent capacitance and C1, C2, C3, etc. are the individual capacitances.
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() }
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 are the names of the 6 carbon atoms in citric acid?
The six carbon atoms in citric acid are named C1, C2, C3, C4, C5, and C6.
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)
A 10 uF and a 30uF are placed in parallel. What is the resulting capacitance?
Total parallel capacitance is the sum of the value of the parallel capacitors. It uses the formula - Total Capacitance = C1 + C2 + C3. Hopefully, you can do the math at this point.
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.
