here , E = alternate EMF fed
I = alt. current developed
Z = impedance
Phi is the phase rel b/w E and I
cos phi = power factor
Pav  = Av power
XL  = omega L
Xc = 1/ omega C
1) Quantity = E

in L (inductive) -  E = Eocost
in C (capacitive) - E = Eocost
in R (resistive) - E = Eocost
in LR - E = Eocost
in  RC - E = Eocost
in LCR  - E = Eocost
2) Quantity = I
In L ,  I = Iocos (t + (pi/2))
In C , I = Iocos (t + (pi/2))
In R , I = Iocos(t)
In LR , I = Iocos(t - phi)
In RC , I = Iocos(t + phi)
In LCR , I = Iocos(t   + (-) phi)
3)Quantity - Z

in L , Z = XL
in C , Z = Xc
in R , Z = R
in LR , Z = ( R2+XL2)1/2

in CR , Z = (R2 + Xc2)1/2

in LCR , Z = ( R2 + (XL - Xc)2)1/2
4) Quantity - Phi
in L , phi = pi/2
in C , phi = - pi/2
in R , phi = O ,
in LR , phi = tan-1 (XL / R)

in RC , phi = tan-1 (XC / R)

in LCR , phi = tan-1 (XL + XC) / R
 
5) Quantity , cos (phi)...

in L , cos phi = 0
in C , cos phi = 0
in R , cos phi = 1
in LR , RC , LCR (in all 3), cos phi = R/Z

6) Quantity = Pav....=
in L , Pav = 0
in C , Pav = 0
in R , Pav = Iv2R
in LR , RC , LCR , Pav = EVIVcos phi
SELF WRITTEN , HOPE THIS HELPS....
ALL THE BEST :) :)
AND PLZ COMMENT IF U LIKE IT :) :)



I always like to walk in rain as no one can see me crying there :( frnds are like diamonds , if u hit them , they don't break but they slip frm ur hands -----It is better to be hated for what you are than to be loved for what you are not.---- *****wen love and skill work together--expect a masterpiece*****
