If we do them as if they are easy they will be easy...n if we think them to be difficult they will be difficult.....ALL THE BEST FRNDS...!!!!!!!!!
V=IZ
z=impedence
Z=(R^2+(XL-XC)^2)^1/2
XL=VL/I=10000
XC=VC/I=6000 ----> Z=4123.1056
V=4123.1056*3*10^-3
V=12.369

Vinodhine the value of R = 1000 that is 1K but u have taken as 100.
Galit garg is right.
I = v/z => v = I * z = 3m * sqrt(17)*k = 3 * 4.123 = 12.37v

Swathi, you have to consider the R value as 1 Kohm, and dont forget to note the current is in milliampere so resistance will be in Kiloohms

XL=VL/I=10 and XC=VC/I=6
Z=sqrt of (100)2+(6-10)2=10016 i got
V=I*Z
=3*10016
=300.239904077 i got but the given answer is not come how to solve to get that answer.

VL=I*XL , VC=I*XC
XL=?,XC=?,R=1000
Z=UNDERROOT OF R2+(XC-XL)2
V=I*Z=12.37
XL=?,XC=?,R=1000
Z=UNDERROOT OF R2+(XC-XL)2
V=I*Z=12.37
