In a parallel circuit, et = 277 v, r = 33 kω, and xl = 42 kω. what is z?

Given:

Resistance

Inductive reactance

We can calculate total impedance (Z) in parallel circuit, by using a reciprocal formula (identical to that used in calculating parallel resistances in DC circuits) as follows.

solving this we get, Z = 18.4798 kΩ

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
