Thevenin equivalent

Question

Answer 1

Step 1:

Find the Thevinins 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 .

.

Above resultant is in series with resistance .

Equivalent resistance is .

.

Thevenin's equivalent resistance is .

Solution :

Thevenin's equivalent resistance is .
