In an ac circuit the potential differences across an inductance and resistance joined in series are, respectively, 16 V and 20 V. The total potential difference across the circuit is

Options

A. 20 V
B. `25.6 V`
C. `31.9V`
D. `53.5 V`

Explanation

`V _(rms) = sqrt(V _(R) ^(2) + V _(L) ^(2))= sqrt ((20 ) ^(2) + (16) ^(2)) = 25.6 `
