6. UMF 3.78 3.78 Obtain the Thévenin equivalent of the circuit to the left of terminals (a, b) in Fig. P3.78. Use your result to compute the power dissipated in the 0.4 S2 load resistor. 322 Figure P3.78: Circuit for Problem 3.78.

Answer 1

The Thouining Resistance is found by open Concerting this current Soule and shoot Creting the voltage Source.
