An rms voltage of 110 V is applied across a series circuit having a resistnce `11 Omega` and an impedance `22 Omega`. The power consumed is

A

(A) `275 W`

B

(B) `366 W`

C

(C) `550 W`

D

(C) `1100 W`

Text Solution

Verified by Experts

The correct Answer is:
A
`P=(E_V) (I_V) cos phi, P=(E_V) (E_V)=(Z) (R )/(Z)`
or ` P=(E_(V)^(2)R)/(Z^(2)) = (110 xx 110 xx 11)/(22 xx 22) = 275 W`.
