For a certain load, the true power is 150 W and the reactive power is 125 VAR. The apparent power is

[A]. 19.52 W
[B]. 195.2 W
[C]. 275 W
[D]. 25 W

Answer: Option B

Apparent Power = 125+ 150 =275/1.41=195.2w

The above solution is wrong

The correct one is sqrt( 125^2 + 150^2 ) = 195.2

Units should be in VA. i.e. 195.2VA.
True power - Watts.
Reactive power - VARS.
Apparent power - VA/KVA.

kva = sqrt(true power)*sqrt(reactive power).

kva = square root of kw^2+kvar^2.

@Manikant.

By the help of your formula, the answer which outputted is not matched with given option. So please explain in detail.

@ALL.

(app)^2=(tru p)^2+(react p)^2.
so, app p=sqrt of tru^2+react^2.
