A parallel-plate capacitor has the capacitance of C1 = 15 \mu F when the distance of the two plates is d = 18 cm. A battery with the emf = 3 V is used to charge the capacitor.
How much charge can be put on the parallel-plate capacitor? ( note that for micro, 10-6, you can use u for \mu .)
45*10^-6
C
Correct response: 4.5E-5 C \pm 5.0%
Now, consider the following two cases separately:
Case 1: if the emf stays connected, but the distance of the parallel plates is changed to d2 = 6 cm.
2. What is the new capacitance C2 and how much is the charge Q2 in the capacitor?
