Concept:

When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitors' capacitances.

Ceq(parallel)=C1+C2+C3++C4

When capacitors are connected in series, the total capacitance is less than the least capacitance connected in series.

1Ceq(series)=1C1+1C2++1Cn

Calculation:

For the two 6 F capacitors connected in parallel, the resultant capacitance will be:

Cnet = 6 + 6 = 12 F

Also, the two 2F capacitors connected in series connection will be equivalent to a single capacitor of value:

Cnet = 2/2 = 1 F

The resultant circuit is drawn as:

F2 Shubham Bhatt 3.3.21 Pallavi D8

Since the 1 F and 12 F capacitors are connected in parallel, the net capacitance will be:

Cnet = 1 + 12 = 13 F
