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 = Eocos
t
in C (capacitive) - E = Eocos
t
in R (resistive) - E = Eocos
t
in LR - E = Eocos
t
in RC - E = Eocos
t
in LCR - E = Eocos
t
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 :) :)
