What is the capacitance (C) of a parallel plate capacitor with area A and separation d?
C = ε * A / d
C = A / (ε * d)
C = ε * d / A
C = A * d / ε
Questions & Step-by-Step Solutions
What is the capacitance (C) of a parallel plate capacitor with area A and separation 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 (A) of one of the plates. This is the surface area of the plate.
Step 3: Determine the separation (d) between the two plates. This is the distance from one plate to the other.
Step 4: Know that ε (epsilon) is a constant called permittivity, which depends on the material between the plates (the dielectric).
Step 5: Use the formula for capacitance: C = ε * A / d. This means you multiply the permittivity (ε) by the area (A) and then divide by the distance (d).
Step 6: Calculate the capacitance (C) using the values you have for ε, A, and d.
