I=V/Z
I=10/SQRT(R+XL)
I=10/SQRT(1000+(1/2*3.142*5K*24m))
SO V=IR
I=10/SQRT(R+XL)
I=10/SQRT(1000+(1/2*3.142*5K*24m))
SO V=IR

Where Z=sqrt((R^2)+(XL^2))
XL=2*Pi*F*L ==> 2*3.14*5K*24m ==> 753.6
VR=I*R
substituting the values:
Z=sqrt((1k^2)+(753.6)^2) ==>1252.16
I=10/1252.16 ==>7.98mA
Finally VR=7.98m*1K ==>7.98V
XL=2*Pi*F*L ==> 2*3.14*5K*24m ==> 753.6
VR=I*R
substituting the values:
Z=sqrt((1k^2)+(753.6)^2) ==>1252.16
I=10/1252.16 ==>7.98mA
Finally VR=7.98m*1K ==>7.98V

Small correction is there on the answer clarification.
Voltage V=IR not VR.
Voltage V=IR not VR.

I = V/Z.
Z = ROOT(R^2 + XL^2).
XL = 2Pi*F*L.
XL = 2*3.143*5000*.024.
XL = 754.32.
Z = ROOT(1000^2 + 754.32^2 ).
Z = ROOT(1000000+ 568998.662).
Z = ROOT(1568998.662).
Z = 1252.59.
Vs = 10v.
Z = 1252.59Ohm.
I = 10/1252.59.
I = 0.00798Amp.
Voltage dropped across the resistor R1, R1 = 1000Ohm.
V = I*R1.
V = 0.00798*1000.
V = 7.983volt.
Z = ROOT(R^2 + XL^2).
XL = 2Pi*F*L.
XL = 2*3.143*5000*.024.
XL = 754.32.
Z = ROOT(1000^2 + 754.32^2 ).
Z = ROOT(1000000+ 568998.662).

Z = 1252.59.
Vs = 10v.
Z = 1252.59Ohm.
I = 10/1252.59.
I = 0.00798Amp.
Voltage dropped across the resistor R1, R1 = 1000Ohm.
V = I*R1.
V = 0.00798*1000.
V = 7.983volt.

Is there in any shortcut method to avoid all such tedious calculations.

Why can't I use voltage divider in this case.
Such that, Vs = Vr * [R1/(R1+RL)].
Such that, Vs = Vr * [R1/(R1+RL)].

Why it can't be solved by using VTG divider?

Voltage divider have a been done between two resistor not unlike impedance.

Inductor is a storing element then why there is a voltage drop?
