AC circuit analysis involving resistors and inductors

Click For Summary

Discussion Overview

The discussion revolves around analyzing an AC circuit that includes resistors and inductors, specifically focusing on finding the currents I1 and I2. The context includes coursework from a university setting.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant requests assistance in solving the circuit for currents I1 and I2, expressing uncertainty about where to begin.
  • Another participant suggests reorganizing the circuit for clarity by moving capacitors next to their respective resistors and converting inductors and capacitors to reactance.
  • The same participant proposes writing the impedances as complex numbers and transforming Y to delta to eliminate floating nodes.
  • A later reply confirms that the inquiry is related to university coursework and asks how to convert inductance and capacitance to reactance.
  • Another participant provides the formulas for converting inductance and capacitance to reactance, indicating that the angular frequency ω is also relevant.

Areas of Agreement / Disagreement

Participants appear to agree on the need to convert inductors and capacitors to reactance, but the discussion remains unresolved regarding the specific steps to take and whether voltages should also be converted to complex numbers.

Contextual Notes

There are limitations in the discussion, including missing assumptions about the circuit configuration and the specific values for frequency and components, which may affect the calculations.

Poster has been reminded (again) to show their work on schoolwork problems
Summary:: Hi anyone can explain me how to solve this circuit, finding the current I2 and I1?
Really don't know where to start Thanks

Is this school work?
Make it easier to recognise the circuit by first migrating C1 to be next to R1. Then C2 to be next to L2. Make the base line ground.

Convert L and C to reactance. Then write the three impedances composed of series R, L & C as complex numbers, Z = R + Xj .

Transform Y to delta. https://en.wikipedia.org/wiki/Y-Δ_transform
Now there are no floating nodes.
You have voltage and phase, convert them to complex.
Work out the currents from there.
 
Hi thanks for your help, yes it's a coursework from uni
How do i convert the L and C to reactance by the way?

Should i have to convert also the voltages as complex number too?

Thank you

XL = ω⋅L
XC = -1 / ω⋅C
ω=2⋅π⋅f
