19.5 Exercise 5

Avg difficulty 2.5

A student was changing one of the dimensions of a square parallel plate capacitor and measuring the resultant charge in a circuit with a battery. However, the student forgot which dimension was being varied, and didn’t write it or any units down. Given the table, which dimension was it?

Dimension Charge(µC)
1.00 0.50
1.10 0.61
1.20 0.71
1.30 0.86
  1. The distance between the plates
  2. The area
  3. The length of a side
  4. Both the area and the length of a side
