1. ECE 201 Circuit Theory I1 Thevenin Equivalent for a circuit containing a dependent source

2. ECE 201 Circuit Theory I2 Determine the Thevenin voltage V Th + V Th - I 20 I

3. ECE 201 Circuit Theory I3 Determine the Thevenin resistance R Th De-activate the independent voltage source and excite the circuit from the a-b terminals with either a voltage or current source. Here, use a voltage source – then we will know the dependent voltage and dependent current.

4. ECE 201 Circuit Theory I4 Thevenin Resistance (continued) ITIT Apply voltage V T and determine the current I T. The Thevenin Resistance will be R Th = V T / I T.

5. ECE 201 Circuit Theory I5 Thevenin Resistance (continued) ITIT I 20 I
