Question

In a parallel circuit, the supply voltage is 120 V, 60 Hz. The resistance is 30 Ω and the inductive reactance is 40 Ω. What is the value of the inductor?

Answer 1

Given : supply voltage = 120V;60 Hz

Inductive Reactance
`(X_(L)) = 40` Ω

The inductive reactance is given by the formula,
`X_(L)=Lw`, where L is inductance and
`w` is given by formula,
`w = 2\pi(frequency)`

Apply this, we can say that,
`L = (X_(L))/(2\pi (frequency))  = (40)/(2(3.14)(60)) = 0.106157 H = 106.157 mH`
