Question

Three capacitor of capacitance 2pf, 3pf and 6pf are connected in series. The equivalent capacitance is

Answer 1

Answer:

1pf

Explanation:

The formula for the capacitance connected in series is: Ceq.=1/c1 +1/c2

Therefore equivalent capacitance = 1/2 +1/3 +1/6 =1

Answer 2

Solution:

let, c1 be the capacitor of capacitance 2pf.

c2 be the capacitor of capacitance 3pf.

c3 be the capacitor of capacitance 6pf.

C eq be the equivalent capacitance of c1, c2 and c3.

here, given in the question that

c1 = 2pf

c2 = 3pf

c3 = 6pf

now, we know that

1/C eq = 1/c1 + 1/c2 + 1/c3

1/C eq = 1/2 + 1/3 + 1/6  

1/C eq = (3+2+1)/6

1/C eq = 6/6 = 1

C eq = 1pf.

therefore, the equivalent capacitance is 1pf.
