Q: What is the effect of increasing the plate area of a capacitor on its capacitance?
Solution: Increasing the plate area A of a capacitor increases its capacitance, as C is directly proportional to A.
Steps: 6
Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy.
Step 2: Know that capacitance (C) is a measure of how much charge a capacitor can store per unit voltage.
Step 3: Learn the formula for capacitance: C = ε * (A / d), where ε is the permittivity of the material between the plates, A is the area of the plates, and d is the distance between the plates.
Step 4: Focus on the area (A) in the formula. If you increase the area of the plates, you are increasing A.
Step 5: Since capacitance (C) is directly proportional to the plate area (A), increasing A will increase C.
Step 6: Conclude that increasing the plate area of a capacitor results in a higher capacitance.
