Week 8 Capacitors

Today we learned about capacitors.  Here we learned about variable capacitors where capacitance is determined by the distance of the aluminum plates.

 Our thoughts on how to construct a variable capacitor.

 Here we used source transformation to solve for voltage across the 4k and 2k resistors.  Then we solved for energy across the capacitance.

Checking our work by the professors solution.

The graphs for the sinosoidal and triangular waves for our experiment.

 The circuit for the experiment.

We ended the day with a lecture on inductance.
