/!\dependant & independant sources/!\

hi

can any one explain to me why I cant use ohm's law here , further the current division and voltage division rules , whenever there is several sources like the circuit above???

regards.....

 

I can't see the "circuit above". It may be that the spelling of "dependant" & "independant" has damaged my eyes.

 

same here.

 

Please retry attaching your file or image.

Thanks,

the dependant source destroys the ability to do simple ohms law, you need to analyze the circuit with the current from the dependant source as a known value. you do this by applying a test voltage to Vs as an independant voltage source, which will also apply a test current Is. from here, use a mesh analysis, and when you write out the system of equations from that, you will work out the dependant source. from there, when you find the current across the series resistors, one of which being your RL, you can find the voltage using your voltage division
