In a parallel circuit, et = 240 v, r = 330 ω, and xl = 420 ω. what is z?

Z = 258Ω

Step-by-step explanation:

There are two methods of solving this question,

First method

Z = ( RXL)/ sqr rt ( R²+XL²)

Z= (330 Ω × 420 Ω)/ sqr rt ( 330 Ω² + 420 Ω²)

Z = 138600 Ω /534

Z = 259  Ω

THE second complete method is given in attachment below

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

answer: 20
