Find Thevenin's Voltage (VTH) Across Resistor R3 - Thevenin Theorem

[Loke]

Find the the equivalent Thevenin’s Voltage (V_TH) across resistor R₃ for the circuit.

-can anyone tell me what's your answer for the solution?
-if i want to use current divider rule...how am i going to solve it?

attempt solution:
Vth=VR3=R3/(R1+R3+R2)*V
= 8.33v

To find Thevenin voltage across R3, remove R3 from the circuit. Find current flowing in the circuit and from this find voltage drop across all resistors. Now find voltage difference across the points where R3 was present. That will give you the Thevenin voltage across R3.

Is my attempt solution correct? oh i know ady...thanks karthick...^^ my answer is wrong.Should be V=11.78v

Yes your answer is right, it is 11.7V
