Question

In a parallel circuit, ET = 120 V, R = 470 Ω, and XL = 500 Ω. What is the reactive power?

Answer 1

Reactive power is 28.8VARs

Explanation:

We are given that in a parallel circuit,
`E_(T)=120V`,R=470Ω and
`X_(L)`=500Ω

And we area asked to find reactive power.

Reactive power is power dissipated due to reactive elements in the circuit and it occurs when voltage and current are not in phase.

Reactive power =
`(E_(T)^(2))/(X_(L))=(120^(2))/(500)=28.8VARs`
