17.

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

Explanation:

No answer description available for this question.

 Shital Hadiyal said: (Jul 30, 2011) Apparent Power = 125+ 150 =275/1.41=195.2w

 Pradeep said: (Sep 17, 2011) The above solution is wrong The correct one is sqrt( 125^2 + 150^2 ) = 195.2

 E.Carlo_Ee said: (May 3, 2013) Units should be in VA. i.e. 195.2VA. True power - Watts. Reactive power - VARS. Apparent power - VA/KVA.

 Manikanta said: (Nov 29, 2013) kva = sqrt(true power)*sqrt(reactive power).

 Durga Prasad said: (Jun 13, 2015) kva = square root of kw^2+kvar^2.

 Bimal said: (Jan 15, 2017) @Manikant. By the help of your formula, the answer which outputted is not matched with given option. So please explain in detail.

 Manju said: (Sep 12, 2017) @ALL. (app)^2=(tru p)^2+(react p)^2. so, app p=sqrt of tru^2+react^2.

 Madhuri said: (Jan 11, 2018) How to convert VAR power into Watt?

 Haris said: (Jan 11, 2020) The answer should be 195.25 VA.
