 Asdfghj said: (Jan 25, 2011) I = Vs/(Rt^2+Xt^2) I= 20/(66^2+47^2) = 246.88mA = 247mA

 Vimal said: (Apr 4, 2011) v/sqrt(R2+X2)

 Mani said: (May 28, 2011) Vimal is ryte.

 Hussain said: (Jun 1, 2011) RT = 66 ohms which is a total resistance of circuit. XT = 47 ohms whihc is a total reactance of Xc and XL. z = sqrt(R2 + X2) I = Vs / z;

 Anila said: (Aug 6, 2011) Vs=IZ Z=SQRT(R^2+Xt^2); Z=81.0246; I=Vs/Z; I=20/81.0246; I=246mA...

 Science Mani said: (Apr 8, 2013) I=Vs/Z; Z=sqrt(R^2+X^2);

 Krupa said: (Feb 28, 2014) Z = sqrt((66^2)+(47^2)). Z = 81.024 ohms. V = IZ. I = V/Z = 20/81.024 = 0.24684 = 246.84mA = 247mA.

 Anamika said: (Jun 28, 2014) I = V/Z. I = 20/sqrt(66^2+47^2). I = 0.24684 apro. I = ~247mA.

 Vikash Baghel said: (Aug 9, 2017) Very nice, Thanks.

 Naveen said: (Aug 29, 2017) You are correct @Anila.

 Kamini said: (Oct 2, 2018) Your solution is very easy, thanks @Anamika.

 Mukesh Soni said: (May 20, 2019) Rt= 66 * 66= 4356 Xt= 47 * 47= 2209 Z= √1/2 (4356+2209) √1/2 ( 6565). Near about = 82, I = v/ z, I =20/82 =247map.
