Question

How are the capastors joined in series? Draw
the diagram and obtain expression for equivalent
capacitance​

Answer 1

Answer:

Consider that three capacitors having capacitance C1,C2 and C3 are connected in series to each other shown in the figure above,

Consider that +q charge is given to first plat of first capacitor. By induction a charge (−q)will produce at internal surface of second plate of this capacitor and so on.

Consider that potential between the plates of capacitor are C1,C2 and C3 respectively so,
