Question

Determine current through 6 ohm resistance connected across A-B terminals in the electric circuit of Fig. using Thevenin’s Theorem. 

Answer 1

Applying Thevenin’s theorem, after detaching the 6-ohm resitor from terminals A −B,

V_TH = V_C = 15 − 1 × 3 = 12 volts

R_TH = 4 + 3/6 = 6 ohms

I_L = 12/(6 + 6) = lamp
