19. 

If a load is purely inductive and the reactive power is 12 VAR, the apparent power is

[A]. 0 VA
[B]. 12 VA
[C]. 6 VA
[D]. 24 VA

Answer: Option B

Explanation:

No answer description available for this question.

Apparant power = active power + reactive power.
But in purly inductive case active power = 0.
Apparnt power = 0 + 12.
= 12.

Apparent power = Hole under root of (Square of active power + Square of reactive power).

Root of S = root (square of p + square of q).

Subhrajit Jena said: (Mar 20, 2018)  
Apparent power =Reactive power÷sin(90), as it is pure inductive.
Now Apparent power=12÷1=12 VA, the required answer.
