Why create a new unknown variable i2? Instead of creating this unknown current variable, why not create a new voltage variable "v" across the node? Then the current through the 5Ω is a function of v, and ix is a function of v and 10Ω.i did a source transformation . but was kinda stuck with all the variableView attachment 46354
I don't follow how you are getting either of these and I'm not sure you have units that are working out. But it's hard to tell because you don't track units.so, by using supermesh on the 3A current source, i do a KLV on left and right loop. but how should i form the equation for the dependent current source and resisitor?
here what i get:
left mesh:
-50 + 10ix + 2(-vx/4) + 2 (-vx/4)=0
-50+10ix-vx=0
right mesh:
5(ix-vx/4)+4ix + 2(vx/4) + 2 (vx/4)= 0
9ix-1/4vx = 0
I have no idea what might have given you this notion. One of the principle motivations for using a supermesh is to avoid a current source in writing the loop equation but then use the current source to provide the relationship between the multiple mesh currents involved in the supermesh loop. But a blanket statement of just disregarding all current sources doesn't make sense. Remember, there is nothing magical or mysterious here -- this is simply a systematic application of KVL and KCL and Ohm's Law to a circuit.after some reading again, to work with supermesh i have to disregard all current source right?
