An engineering students designs and builds a capacitor from somescrap iron. One piece of iron is a square with side lengths of 10cm, while the other piece is a rectangle that is 20 cm long and 10cm wide. The student knows they can keep the plates separated by adistance of 1.2 micrometers.
a. What is the capacitance of this setup?
b. If the capacitor is fully charged using a 1.5 V battery, howmuch charge is built up on the plates?
c. How much energy is stored?
d. After performing the experiment, the student inserts adielectric with a k value of 1.2. What values would thischange?
