| Apr 25, 2016 at 16:31 | comment | added | The Photon | So I3 is defined as the current through R3 from left to right. Can you write an expression for that current in terms of node voltages? Hint: use Ohm's law. | |

I have included the original question

| Apr 25, 2016 at 16:25 | comment | added | The Photon | Then you can't solve the problem. The controlling element for the dependent source needs to be defined. Your schematic doesn't tell us what it is, so there is not enough information to solve the problem. We can guess that probably I3 is the current through R3, but it should be stated in the problem definition which direction is considered positive and which is negative. | |
| Apr 25, 2016 at 16:24 | comment | added | Eoghan_Mulcahy | Hi @ThePhoton that is my problem at the moment i am not sure how to define it. | |
| Apr 25, 2016 at 16:23 | comment | added | The Photon | You method of converting to Norton equivalents should also work. But you need to define what is "I3". You ought to be able to write I3 in terms of node voltages. | |
| Apr 25, 2016 at 16:21 | comment | added | The Photon | Have you tried making a supernode around the dependent source the same way you would around an independent source? | |
