- Homework Statement
- The current in the 8 - ohm resistor in the drawing is 5 A. Find the current in the 20 ohm and 9 - ohm resistor.

- Relevant Equations
- V = IR

I'm having difficulties finding the current for a 9-ohm resistor only, not the 20-ohm

My attempt was to find the voltage of a 20ohm resistor which is V = (0.75A)(20-ohm) = 15V. I got the 0.75A by adding the currents of the two resistors (8-ohm and 16-ohm) together that were in parallel and it becomes the current that will flow through the 20-ohm resistor. After getting 15V, I don't know what to do next in order to find the current in the 9 - ohm resistor.

Also, look at the image for more information.
