Homework Statement


Circuit.png


So I have to wire the circuit and find R2 by only making another voltage measurement. We know that R3 is equal to 1000 ohms.

Homework Equations





The Attempt at a Solution



So I was thinking that you can find the voltage of R3 and the find the current going through R3. When you have those measurements, you can find the R2 because you know the potential difference by (6-Voltage of R3). Then you use the current found previously, and the ohms law. Is this correct? Thank you

Pradeepk, it would appear that your attachment isn't actually attached.

Yes, it's fine now.

Your method for finding R2 is okay.
