v=10;

total current I =sqrt(Ic^2+Ir^2);

I = sqrt(7.076*10*^-3^2+ 4.608*10*^-3^2);
I= 8.444*10^-3

z = 10/8.444*10^-3= 1184.25~~1192;

If we solve it using Z=sqrt (R^2+Xc^2), the answer is different.

No. This is a parallel RC Circuit, So use the below formula,

Z = RXc/sqrt(R^2+Xc^2).

Can anyone please show the correct solution for this? Thank you!

Total current = square root(Ic^2 + Ir^2).

Z = Voltage/total current = 10/total current.
