Question

Q3. Three capacitors each of
capacitance 3uF are connected in
series. Equivalent capacitance will be
O (a) 4 PF
O (b) 3 PF
O (C) 2 JF
O (d) 1 pF​

Answer 1

Answer:

the answer is 1uF

Explanation:

when the capacitors connected in series

Ceq = 1/C1 + 1/ C2 + 1/ C3

Ceq = 1/3 +1/3 + 1/3

Ceq = 3/3

Ceq = 1 uF

Answer 2

Answer:

The equivalent capacitance will be (d) 1 pF​.

Explanation:

When several capacitors exist connected in a series combination, the reciprocal of the equivalent capacitance exists as the sum of the reciprocals of the individual capacitances. When several capacitors exist connected in a parallel combination, the identical capacitance is the sum of the individual capacitances.

Capacitance exists as the ratio of the amount of electric charge stored on a conductor to a distinction in electric potential. There exist two closely related notions of capacitance: self-capacitance and mutual capacitance.

when the capacitors connected in series

Ceq = 1/C1 + 1/ C2 + 1/ C3

Ceq = 1/3 +1/3 + 1/3

Ceq = 3/3

Ceq = 1 pF
