Answer 1

Answer

• ⇒ Series = 3mF and Parallel = 16 mF.

Explanation

⇒  Given,

• C₁ = 12 mF, and C₂ = 4 mF.

• (i).  Using the formula for Series.

1/C = 1/C₁ + 1/C₂

∴ 1/C = 1/12 + 1/4

∴ 1/C = 1/12 + 3/12

∴ 1/C = 4/12

∴ 1/C = 1/3

∴ C = 3 mF.

• (ii). Using the formula, when they are connected in parallel,

C = C₁ + C₂

∴ C = 12 + 4

∴ C = 16 mF.
