Questions & Step-by-Step Solutions

What is the formula for calculating the capacitance of a parallel plate capacitor?
  • Step 1: Understand that a parallel plate capacitor consists of two flat plates that are parallel to each other.
  • Step 2: Know that the capacitance (C) is a measure of how much electric charge the capacitor can store.
  • Step 3: Identify the variables in the formula: C = εA/d.
  • Step 4: Recognize that ε (epsilon) represents the permittivity of the material between the plates, which affects how much charge can be stored.
  • Step 5: A is the area of one of the plates. The larger the area, the more charge can be stored.
  • Step 6: d is the distance between the two plates. The smaller the distance, the more charge can be stored.
  • Step 7: Combine these elements into the formula: C = εA/d, which tells you how to calculate the capacitance.
