Step 1:

\

Find the thevinins equivalent voltage.

\

1.Open the load resistor.

\

2.Calculate the Open Circuit Voltage. This is the Thevenin Voltage (VTH).

\

Redraw the circuit :

\

Step 2:

\

Find Thevenin Voltage (VTH).

\

Thevenin Voltage VTH  = VR1 + E .

\

VTH  = -4(-4.1) + 7

\

VTH  = 16.4 + 7.

\

VTH  = 23.4.

\

Therefore Thevenin Voltage VTH  = 23.4 V.

\

Solution :

\

Thevenin Voltage is VTH  = 23.4 V.
