Question

What happens to the capacitance of a multi plate capacitor when the number of plates increases?

(a) Increases

(b) Decreases

(c) Remains constant

(d) Becomes zero

I have been asked this question in an interview for job.

My doubt stems from Capacitance of a Multi Plate Capacitor in portion Capacitance and Capacitors of Basic Electrical Engineering

Answer 1

Correct answer is (a) Increases

Easiest explanation: When the number of capacitors increases, the capacitance also increases since it is related by the formula C=Actual permittivity*(n-1)*A/d. Here, we can see that the capacitance is directly proportional to the number of capacitors.
