The most common capacitor is known as a parallel-plate capacitor which involves two separate conductor plates separated from one another by a dielectric. Capacitance (C) can be calculated as a function of charge an object can store (q) and potential difference (V) between the two plates:
Final answer: When the dielectric of a capacitor is broken down, excessive current will flow through the dielectric, shorting it. When a dielectric is inserted into a charged capacitor, it becomes polarized and reduces the electric field strength inside the capacitor, resulting in a smaller voltage between the plates for the same charge.
