Thevenin circuit

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 Voltage (V_TH).

Redraw the circuit by using source transformation at the second end.

The voltage across the resistor .

Redraw the circuit :

Apply KVL to the first loop :

Voltage drop across resistor :

Voltage drop across resistor is .

Step 2:

Apply KVL to the second loop :

Voltage drop across resistor :

Voltage drop across resistor is .

Voltage drop across terminals A and B :

Thevenin's  equivalent Voltage is .

Solution :

Thevenin's  equivalent Voltage is .
