Homework Help: Need help on series circuts

300ma = 9/R
Total Resistance = 30Ohms

30/2 = 15ohms each resistor?

 

I am redrawing the circuit, hopefully this is easier to look at:

Code (Text):

 ________300ma__
|               |
|               ∏ L1  
_ +             |  R1      
9v              |
- -             ∏ L2
|               |  2R
|_______________|

Are you sure you reproduced the question accurately? It's weird to have those inductors in there, without for example a switch that closes at time t=0 or something along those lines. Also, is the 300 mA the current at some specific time, or after a long time has passed?

Also, did you mean to say 2R or R2 in the figure?

If R were 300 ohms, then the current would be 9/300≠0.3A.

 

I mean 30 Ohms, the O makes it look like a 300
