Thevenin and Norton circuit

Analog Signal Processing 2012

Find the Thenevin and Norton equivalent circuit for the below ones. 1. Open-circuit voltage can be found by placing a capacitor at the

terminals that you want determine the Thevenin’s equivalent circuit.

2. Short-circuit current can be determined by short-circuiting the terminals that you want to determine the Norton’s equivalent circuit.

3. The Thevenin or Norton resistance is determined by test signal method. Apply an independent current source of 1Adc at the terminals that need the equivalent Thevenin or Norton and check the voltage. In this case, the voltage is, in fact, the equivalent resistance.

Note : Perform all of the simulations in Bias Point mode.

DC Sweep Simulation

Analog Signal Processing 2012

Usage : When you want to test the variations of a quantity in the circuit due to the variations of a source or a particular independent quantity. Quantity : voltage, current or power.

You are asked to determine the variation of the current flows through resistor R4 due to the variation of the voltage of V1.

DC Sweep Simulation

Analog Signal Processing 2012

Step 1 : Draw the circuit with all of the values shown. Do not forget to add a ground node, otherwise your circuit will be floated. The independent voltage source should be added with a nominal value. Step 2 : Create a new simulation profile and choose the simulation mode as DC Sweep.

Sweep variable : V1 Range : 0 Vdc – 10 Vdc with an increment of 0.1Vdc.
