Question

Three capacitors 2µF, 3µF, and 6µF are joined in series with each other. The equivalent capacitance is ____________.

Options

• 1/2µF

• 1µF

• 2µF

• 11µF

Answer 1

Three capacitors 2µF, 3µF, and 6µF are joined in series with each other. The equivalent capacitance is 1µF.

Explanation:

`1/"C"_("series") = 1/"C"_1 + 1/"C"_2 + 1/"C"_3`

`1/"C"_("series") = 1/2 + 1/3 + 1/6`

`(3 + 2 + 1)/6 = 6/6`

`"C"_("series") = 1mu"F"`
