Q: The capacitance of a parallel plate capacitor is directly proportional to which of the following? (2019)
Solution: Capacitance (C) is directly proportional to the area of the plates (A) and the dielectric constant (ε) and inversely proportional to the distance (d) between the plates.
Steps: 6
Step 1: Understand what capacitance (C) means. It is a measure of a capacitor's ability to store charge.
Step 2: Know that a parallel plate capacitor has two flat plates that can hold electric charge.
Step 3: Learn that the capacitance (C) depends on three main factors: the area of the plates (A), the distance between the plates (d), and the dielectric constant (ε) of the material between the plates.
Step 4: Remember that capacitance is directly proportional to the area of the plates (A). This means that if the area increases, capacitance increases.
Step 5: Also remember that capacitance is directly proportional to the dielectric constant (ε). A higher dielectric constant means higher capacitance.
Step 6: Finally, understand that capacitance is inversely proportional to the distance (d) between the plates. If the distance increases, capacitance decreases.
