A parallel plate capacitor has square plates with ege length 8.20 cm and 1.30 mm separation. (a) Calculate the capacitance. (b) Find the charge for a potential difference of 120V.

Explanation

To solve the problem step by step, we will first calculate the capacitance of the parallel plate capacitor and then find the charge stored in it when a potential difference is applied.

### Step 1: Calculate the Area of the Plates
The area \( A \) of one square plate can be calculated using the formula:
\[ A = \text{edge length}^2 \]
Given that the edge length is \( 8.20 \, \text{cm} = 0.0820 \, \text{m} \), we can calculate:
