Please give me the solutions of these kinds of problems.

I = Vs/(Rt^2+Xt^2)

I= 20/(66^2+47^2) = 246.88mA = 247mA

v/sqrt(R2+X2)

Vimal is ryte.

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;

Good answer.

Vs=IZ
Z=SQRT(R^2+Xt^2);
Z=81.0246;
I=Vs/Z;
I=20/81.0246;
I=246mA...

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.

I = V/Z.
I = 20/sqrt(66^2+47^2).
I = 0.24684 apro.
I = ~247mA.

Hai @Anamika

Your solution is easy to understand. Thankyou.

Very nice, Thanks.

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

Your solution is very easy, thanks @Anamika.

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.
