Discussion Overview

The discussion revolves around the application of the current divider formula to find the current I3 in a given circuit configuration. Participants are exploring the methodology for applying the formula, specifically whether it can be used directly or if additional steps are necessary.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant asks if the current divider formula can be used directly to find I3.
  • Another participant suggests that the current divider must be used twice, first to combine resistors R2, R3, and R4 into a single equivalent resistor before calculating the current through that combination to find I3.
  • A later reply prompts the original poster to show their work based on the advice given, indicating a need for further clarification or demonstration of understanding.

Areas of Agreement / Disagreement

There is no consensus on whether the current divider formula can be applied directly, as one participant suggests a more complex approach involving multiple applications of the formula.

Contextual Notes

Participants have not provided specific details about the circuit configuration or the values of the resistors involved, which may affect the application of the current divider formula.

Hi I want someone to guide me through this by using current divider, where I want to find I3. Can I use the current divider formula directly or?

You must use the current divider twice.
First associate R2, R3 and R4 in a single resistor and calculate the current through the association, then use this current to calculate i3.
