Q: What is the effect of increasing the plate area of a parallel plate capacitor on its capacitance? (2022)
Solution: Increasing the plate area A of a parallel plate capacitor increases its capacitance, as C = ε₀A/d.
Steps: 5
Step 1: Understand what a parallel plate capacitor is. It consists of two plates that store electric charge.
Step 2: Know the formula for capacitance (C) of a parallel plate capacitor: C = ε₀A/d.
Step 3: Identify the variables in the formula: ε₀ is a constant (the permittivity of free space), A is the area of the plates, and d is the distance between the plates.
Step 4: Focus on the area (A) of the plates. If you increase A (make the plates larger), you are increasing the capacitance (C).
Step 5: Conclude that increasing the plate area leads to a higher capacitance because C is directly proportional to A.
