Question

A parallel plate capacitor consists of two plates of area 15cm^2 seperated by sheet of paper 0.5 mm thick. a)Calculate the capacitance? b)If a potantial difference of 200 V is applied across theplates,Calculate the charge? c) if the paper sheet is removed without any loss ofcharge,Calculate the new voltage across the plates?

Explanation / Answer

put the values in metric units into the formula for platecapacitor capacitance did your problem specify whether paper has a dielectric constan? Iassume not, but if it did then use the epsilon value to modify the result above now you can calculate the charge using the other formula forcapacitance, which links voltage and charge to C
