Thevenin equivalent circuit

Question

Answer 1

Step 1:

Find the Thevein's equivalent resistance.

1.Open the load resistor.

2.Open Current Sources and Short Voltage Sources.

3.Calculate the Open Circuit Resistance. The resultant open circuit resistance is the thevenin's Resistance (R_TH).

Redraw the circuit :

Observe the circuit,

The Resistors  and are in series.

.

Above series resultant comes in parallel with the resistance .

.

The Resistors  and are in series.

.

Above series resultant comes in parallel with the resistance .

Thus, the resultants ,  and are in series.

Equivalent reistance is .

.

Thevenin's equivalent resistance is .

Solution :

Thevenin's equivalent resistance is .
