Thevenin equivalent circuit

Question

Answer 1

(1)

Step 1:

Find the Thevenin's equivalent resistance.

1.Open the load resistor.

2.Open Current Sources and Short Voltage Sources.

3.Calculate the Open Circuit Resistance. This is the Thevenin Resistance (R_Th).

Redraw the circuit :

Maximum power will be transferred when source resistance and load resistance are equal.

Step 2:

and are in parallel.

, and are in series.

Thevenin's resistance is .

Solution :

Thevenin's resistance is .
