What is the capacitance of a parallel plate capacitor with area A and separation d?
Correct Answer: C = ε₀ * A / d
- Step 1: Understand that a parallel plate capacitor consists of two flat plates that are parallel to each other.
- Step 2: Identify the area of the plates as A and the distance between the plates as d.
- Step 3: Know that the capacitance (C) is a measure of how much electric charge the capacitor can store.
- Step 4: Learn the formula for capacitance of a parallel plate capacitor: C = ε₀ * A / d.
- Step 5: Recognize that ε₀ (epsilon naught) is a constant called the permittivity of free space, which helps in calculating capacitance.
- Step 6: Plug in the values of A (area) and d (separation) into the formula to find the capacitance.
