Question

Which capacitor is required in series with 12 farad to get an equivalent

capacitance of 4 farad.​

Answer 1

Explanation:

6 farad capacitor is required in series with 12 farad to get an equivalent

Answer 2

Answer:

6 farad

Explanation:

Capacitor is required in series with 12 farad to get an equivalent  capacitance of 4 farad is as follows:-

For Capacitance in series,

1/C1 + 1/C2 = 1/equivalent  capacitance

Given that C1 = 12 farad, equivalent  capacitance  = 4 farad

1/12 + 1/C2 = 1/4

Solving, we get C2 = 6 farad
