First Part: Capacitance and Area C=↋₀A/d:
In this part the distance, d, between the plates is kept constant d= 10x10 -3m and
the area of the plates is changed. You are to record the values for area (in m2) and
the capacitance C (in F). Take at least eight values of A and C, and then fill the table
below:
