    I'm trying to calculate the y-parameter y12f= i1/v2 when v1=0 which means that the terminals of v1 are shorted together (i think). I came up with the expression of v2= i2(100k + 100k||25k). I also have the equation that from the current divider -i1= i2 *[25k/(25k+100K)]. Although I could substitue in the equation solved for -i1 into my expression I don't believe this is totally right. What am i missing here?
