Week 4 day 8

Today we learned how to find R Thevenin and V Thevenin.  By using circuit analysis in this case superposition and source transformations we easily found Vth and Rth.

An exercise on source transformations to find the current i0.

Here we short the voltage an set the current to open to find Rth and use source transformation to find Vth.

Another excercise where we solved for Vth and Rth.

An excercise using mesh current analysis to find the current and  then we found Vth and solved for Rth.

A picture on how the potentiometer works and the graph we should get from our experiment.

 Here we tested the values of the potentiometer to get the voltage from each value of the resistance inside it.

Here is the graph of the table P vs R
