A nerve signal is transmitted along a nerve axon which is modelled as a capacitor with area A1 and plate separation d1. Assume that the expression used for the uniform parallel plate capacitor is valid. The initial capacitance is C1. If the area A is decreased to 0.9 A1 and the plate separation is increased to 1.2 d1, which of the following best describes the new capacitance?
Select one: a. 0.75C1 b. 1.08C1 c. C1 d. 1.33C1 e. 0.927C1
