In a parallel plate capacitor, if the distance between the plates is increased, what happens to the capacitance? (2022)
Step 1: Understand what a parallel plate capacitor is. It consists of two plates that store electric charge.
Step 2: Know that capacitance (C) is a measure of how much charge a capacitor can store.
Step 3: Learn the formula for capacitance in a parallel plate capacitor: 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: Notice that in the formula, capacitance (C) is divided by the distance (d). This means that as d increases, the value of C decreases.
Step 5: Conclude that if the distance between the plates is increased, the capacitance of the capacitor decreases.
