Question

Answer 1

  

(2)

Step 1:

Find the Thevenin's equivalent voltage.

1. Open the load resistor.

2. Calculate the Open Circuit Voltage. This is the Thevenin's Voltage .

Redraw the circuit :

The network has two independent loops.

Find the current in each loop.

Apply KVL to the Loop 1:

.

Voltage at node A  :

.

Step 2:

Apply KVL to the Loop 2:

.

Voltage at node B  :

.

Step 3:

Find Thevenin's Voltage .

Thevenin Voltage .

.

Therefore Thevenin's Voltage is .
