110`underset(rms)(V)` is applied across a series circuit having resistance `11 Omega` and independence `22 Omega` . The power consumed is

A

275 W

B

366 W

C

550 W

D

1100 W

Text Solution

Verified by Experts

The correct Answer is:
A
P = `underset(rms)(V)``underset(rms)(V)``underset(rms)(I)`cos`phi`
= `underset(rms)(V)`(`underset(rms)(V)`/Z)(R/Z) = `(110)^(2)`(11)/`(22)^(2)` = 275 W
