A parallel-plate capacitor has the capacitance of C₁ = 10 µF when the distance of the two plates is d = 18 cm. A battery with the emf = 8 V is used to charge the capacitor. How much charge can be put on the parallel-plate capacitor? (note that for micro, 106, you can use u for μ .) Number Units Correct response: 8E-5 C ± 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? C₂ Number Units Correct response: 3E-5 F ± 5.0% Q₂ Number Units Correct response: 2.4E-4 C = 5.0% Case 2: After the initial charging, the emf is removed. Therefore, the amount of charge you calculated from the question #1 remains in the capacitor. Now, again, the distance of the parallel plates is changed to d₂ =6 cm. What is the potential difference V₂ across the capacitor? V₂ Number Units
