Note: the circuit for this question is illegible in the source scan, so the numerical answer cannot be computed here. The complete Thevenin procedure the examiner expects is given below; apply it to the circuit printed in the paper.

  1. Remove the load (the 8 Ω resistor) and label its terminals A and B.
  2. Find Vth = open-circuit voltage VAB using KVL/mesh, nodal analysis, voltage division or source transformation on the remaining circuit.
  3. Find Rth: replace every independent voltage source by a short circuit and every independent current source by an open circuit (keeping internal resistances), and compute the equivalent resistance seen from A–B (series/parallel or star–delta).
  4. Draw the Thevenin equivalent: Vth in series with Rth, and reconnect the 8 Ω across A–B.
  5. Load current: \[ I_{8\Omega} = \frac{V_{th}}{R_{th} + 8} \] with direction from the + terminal of Vth through the 8 Ω.
      R_th
  +--/\/\/--+---- A

 V_th      8 ohm   I = V_th / (R_th + 8)
