B. INTRODUCTION
The purpose of this lab was to:
1. Measure the capacitance of capacitors made out of aluminum foils and plain white
papers made as the dielectric.
2. Measure the capacitance of these capacitors in series and parallel configuration.
3. Investigate if the relationship of capacitance to plate area behaves as expected
4. Investigate if the relationship of capacitance to plate separation behaves as
expected
5. Measure the dielectric constant of the type of paper used in this experiment
The capacitor was made by sandwiching notebook papers between two aluminum foils held
together by paper clips. The capacitance between the aluminum foils was measured using a
multimeter. The thickness of the papers was measured using a micrometer.
The unit of capacitance is Farads. 1 Farad=1 Coulomb/ 1 Volt. The capacitance of a capacitor
separated by vacuum is derived from the formula given below.
