combination.

Ans: 22uF
Q7. You are given 3 capacitors each of capacitance
9uF. In how many ways can they be combined
?What will be the effective capacitance in each
case?

Q8. The effective capacitance of two condensers
are 3uF and 16uF when they are connected in
series and parallel respectively. Compute the
capacity of each condenser.

Ans: 12uF and 4uF
Q9. A parallel plate capacitor consists of two identical
circular plates of radius 3cm which are separated
by 2.5mm, calculate the capacity. What will be its
capacitance if the separation is reduced to half the
initial value.

Q10. The effective capacitance of two capacitors
is 4uF in series and 25uF in parallel. Find the
individual capacitance.

Ans: 20uF and 5 uF
Q11. Two capacitors 2uF and 1.5uF are connected
in series and two other capacitors of 3 uF and
6uF are connected in series. The series
combinations are then connected in parallel with
each other. Find effective capacitance of the
combination.

Ans: 2.857 uF
Q12. Calculate the capacitance of a capacitor made
of two parallel metal plates of area 1.571 sq.m.
each, separated by a distance 0.01mm, the
space between the plates being filled with a
medium of dielectric constant 2.5.

(€ = 8.854x10-12F/m)
