Question

10. Suppose you have an unmarked capacitor that resembles neither the blue capacitor or the silver capacitor. Using only the things that we had and used in class, what experiment could you do to determine its capacitance relative to one of the aforementioned capacitors? Describe the experiment and how you would be able to know which has the larger capacitance.

Answer 1

As mentioned the capacitor is unmarked as it do not have any markings to determine the capacitance from marking, then we can use following procedure.Before that capacitance definition is defined as Charge by potential ratio i.e

1) We can use measure it by using digital CAPACITANCE METER or MULTI METER, it will directly show on screen the value of capacitance by adjusting knobs accordingly to different ranges

2)Another method can be take a known capacitor say of capacitance C_2, and unknown capacitor capacitance is say C_1 , then put both in parallel and measure equivalent capacitance which will be

Also we can measure by putting them in series as

By these methods we can get value of capacitors
