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 Resistance (R_TH).

Redraw the circuit :

The Resistors  and are in parallel.

.

Step 2:

The Resistors  and are in series.

Above resultant is in parallel with the resistor .

Above resistance is in series with .

Equivalent reistance is .

.

Thevinins equivalent resistance is .

Solution :

Thevinins equivalent resistance is .
