Question

Three equal 9pf capacitors are connected in series. Find

Answer 1

Answer:

1/9+1/9=2/9

Explanation:

so capacitor in series .........1/c1+1/c2.........ok so 9pf put in c1 ,c2 so your ans. will came and all value resiprocal by 1 ok

Answer 2

Equivalent capacitance  = 1/(1/C + 1/C + 1C) = 1/( 1/9 + 1/9 + 1/9) = 3pf
