Parallel Plate Capacitor 3) Now we’re going to investigate what happens when we change the dimensions of our capacitor. Firstly, disconnect all meters and the battery a) Vary the area of the plates. How does the Capacitance vary with area A? Show your calculations below b) Vary the separation of the plates. How does the Capacitance vary with the separation d. Show this below. Write down an expression for the capacitance of a parallel capacitor, and calculate the constant of proportionality, ε0. 4) Reconnect the battery and adjust to 1.5 V. Check the View “Electric Field Lines” box, and the C
