In a capacitor, if the plate area is increased while keeping the distance constant, what happens to the capacitance? (2023)
Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy.
Step 2: Know the basic formula for capacitance (C). Capacitance is given by the formula C = ε * (A/d), where C is capacitance, 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 3: Identify the variables in the formula. In this case, we are looking at A (the area of the plates) and d (the distance between the plates).
Step 4: Recognize that capacitance (C) is directly proportional to the area (A). This means that if you increase the area, the capacitance will also increase.
Step 5: Since we are keeping the distance (d) constant, we only need to focus on the change in area (A).
Step 6: Conclude that if the plate area is increased while keeping the distance constant, the capacitance will increase.
