Question

34. When two capacitors of capacitance C
each connected in series, their
equivalent capacitance is
are

​

Answer 1

Answer:

When capacitors are connected in series, the total capacitance is less than any one of the series capacitors' individual capacitances. If two or more capacitors are connected in series, the overall effect is that of a single (equivalent) capacitor having the sum total of the plate spacings of the individual capacitors.

Answer 2

Answer:

When a substance of dielectric constant K is filled in the capacitor, its capacity

==KC

Now two capacitors of capacities KC and C are connected in series, therefore their effective capacitance
