Thevenin Equivalent

Thevenin Equivalent

 

In this experiment we will be investigating a circuit that will be replaced with a Thevenin equivalent circuit. this is a picture of the circuit that will be replaced with  the Thevenin equivalent circuit.

 

 

 

 

 

 

 

we first proceed by calculating our Vthevenal. this was done by calculating our Vx which is the same as Vth. here is a picture of the calculation using nodal analysis. Vth= 8.64 volts

 

 

We also calculated our Rth= Rthevenal. here is a picture of the calculation. which was done by removing the voltage sources and closing the circuit. Rth= 65.94 ohms

 

 

now that we obtain our thevenin circuit, the experiment required a load when 8 volts were in such Rload. here is a calculation of how we obtained the Rload. this was done with Voltage divider Rule. Rload= 824.25 ohms 

 

 

once our calculations were done, we then proceed to build our circuit with the values calculated. here are some pictures of our assembled circuit.

 

 

 

 we also obtained the nominal and measured values of our circuit. here is a table of such measurements.

 

 

 

also the voltage in the Rload 2 = 7.91Volta and the theoretical was 8 Volts  which gave a percent error of 1.122 percent.

 

 

 

we dissembled our circuit and build the original one.

 

 

the voltage on the Rload 2 for this circuit was also 7.91 volts.

 

 

 

before dissembling our circuit we made sure that Vmax supplied to Rload 2 occurs when Rload = Rth. here is the calculation and several other calculations when Rload was different.

 

 

 

 

 

this experiment allow us to conclude that a circuit in fact can be replaced with a thevenin equivalent circuit. The values in this new circuit will be the same as in the original circuit. we also discover that the max voltage supplied to the Rload can be reached when our Rth= Rload.
