Question

A `50 Hz AC` source of `20 V` is connected across `R ` and `C` as shown in figureure.

The voltage across `R` is `12 V`. The voltage across `C` is
A. 8 V
B. 16 V
C. 10 V
D. not possible to determine unless value of R and C are given

Answer 1

Correct Answer - B
`V_(C) = sqrt(V^(2)-V_(R)^(2)) =16 V`
