AI Thread Summary
The discussion focuses on using the current divider formula to find I3 in a circuit. It is suggested that the current divider should be applied twice: first by combining resistors R2, R3, and R4 into a single equivalent resistor to calculate the current through that combination. After finding this current, it can then be used to determine I3. Participants are encouraged to show their calculations based on this guidance. The conversation emphasizes the importance of following the correct steps to achieve the desired result.

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.
