In this experiment we will determine how voltages are distributed in capacitor circuits and explore series and parallel combinations of capacitors. The capacitance is a measure of a device''s ability to store charge. Capacitors are passive electronic devices which have fixed values of capacitance and negligible resistance.
Both fixed and variable types are available. Vacuum variable capacitors can have a minimum to maximum capacitance ratio of up to 100, allowing any tuned circuit to cover a full decade of frequency. Vacuum is the most perfect of dielectrics with a zero loss tangent.

Capacitors can be used in analog circuits as components of integrators or more complex filters and in negative feedback loop stabilization.
The derivation of formulae for capacitors in series and parallel will help to reinforce your students’ understanding of circuits involving capacitors. Your students will have encountered the idea of replacing resistors in series and parallel by a single resistor which has the same effect in the circuit.
Now capacitors are measured in terms of capacitance (C). The unit of capacitance is Farad (F). There are a few ways that you can measure the capacitance of any given capacitor. For all the methods, the first rule is to please discharge your capacitor fully. Else you may harm yourself or can completely damage your testing device.
