Nodal Analysis problem 3.39

[@BelgianJava]

Why is the current trough the current source (2mA) equal to 2/K? This doesnt make sense to me..

[@soccermanabc]

for node voltages aren't you only suppose to choose essential nodes? why was v1 one of your nodes?

[@AraujoMatt]

TheMagicalGarden is right. This is a useful trick, especially if you are trying to solve an equation by hand. I use it to express all terms with a common denominator

[@aldrintranate9506]

because 2/1000=0.002A or simply 2mA

[@themagicalgarden6970]

This is probably because 2/k is the same as 2m.
