An alternating voltage is connected in series with a resistance `R` and inductance `L` if the potential drop across the resistance is `200V` and across the inductance is `150V`, then the applied voltage is

A

350 V

B

250 V

C

500 V

D

300 V

Text Solution

Verified by Experts

The correct Answer is:
B
`v = sqrt((V_(R)^(2) + V_(L)^(2))) = sqrt(200^(2) + 150^(2)) = 250 V`
