# Resister inductor - calculate resulting impedance

resister // inductor -- calculate resulting impedance

Hello,

how 600Ω || 300jΩ = 120 + j240 ??

how do you get the value 120 + j240 from 600 register parallel wih 300jΩ inductor?

Are you tying to ask how to calculate the equivalent resistance of a 600-Ohm resistor in parallel with a 300j Ohm inductor?

how do you calculate this

Welcome to the PF.

Are you familiar with the equation for combining impedances in parallel? Maybe try checking wikipedia for this equation, and post what you find here.

I want to know how 600Ω || 300jΩ is equal with 120 + j240 ???
what do i have to explain about?
how 600 register parallel with 300johm is equal to 120+ j240???????

Well, for starters, stop calling it 'register'. It's a 'resistor'. Do you know anything about electricity?

Now, are you familiar with complex numbers and how impedances are represented?
