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

A

`20 V`

B

`25.6 V`

C

`31.9 V`

D

`53.5 V`

Text Solution

Verified by Experts

The correct Answer is:
B
`V_("net")=sqrt(V_(R)^(2)+V_(L)^(2))=sqrt((20)^(2)+(16)^(2))=25.6`
