Question

The equivalent capacity of two 20 microfarad capacitor in parallel is:

a. 10 Microfarad

b. 20 Microfarad

c. 30 Microfarad

d. 40 Microfarad

Answer 1

Here we have given that ,

Two capacitor connected in parallel having capacitance given as

C1 = C2 = 20 microfarad

Now in case of parallel connection of capacitor the charge across each will be divided directly proportional to their capacitance and voltages across them will be same

So that the net resultant capacitance will be given by simply adding both the capacitor

So thag total capacitance Ct = C1 + C2

Hence equivalent capacity Ct = 20 + 20 = 40 microfarad.

Therefore equivalent capacity of two 20 microfarad capacitor in parallel will be option (d) 40 Microfarad.
