Prerequisites
Lab Activities
Using an electrometer, the students:
1. experimentally confirm the equivalent capacitance relationships for series and parallel capacitance
circuits;
2. experimentally confirm the theoretically predicted equivalent capacitance for two combination
circuits;
3. experimentally measure the capacitance of an unknown capacitor using two methods  charge
sharing and voltage ratio;
4. experimentally measure the capacitance of an unknown capacitor with a capacitance much less than
the standard using the repeated charge sharing method; and
5. experimentally confirm the capacitance relationships in a homework problem given in the writeup.
Quantitative experimental results tend to be within 10% of the expected values.
