Answer:
Apparent power is 17.31Volt-amperes.
Step-by-step explanation:
In a parallel circuit, we are given with [tex]E_{T}=120V[/tex],R=1500Ω and [tex]X_{L}[/tex]=1000Ω.
And we are asked to find apparent power.
Apparent power is the combination of true power and reactive power.
In other words we can say that in a power triangle, apparent power is the hypotenuse where as true power and reactive power are sides.
Let us find true power first.
True power = [tex]\frac{E_{T}^{2}}{R} =\frac{120^{2}}{1500}=9.6watts[/tex]
The Reactive power=[tex]\frac{E_{T}^{2}}{X_{L}}=\frac{120^{2}}{1000} =14.4VARs[/tex]
Now Apparent power=[tex]\sqrt{9.6^{2}+14.4^{2}}=17.31VA[/tex]
