About define variable with solve equation

Hi, All,

I have a question about solve equation,

please check red circle as below,

I've defined Vop1_out at solve equation,

why I need to define it again?

Is there have method to solve this problem??

Thank you all guys

If you get a symbolic solution before you assign values to the variables you can create a numeric function that allows you to investigate trends:

Yes.At the far left of the region where you solve type ":" followed by "v.op1_out" (all without the quotes.

That way you have already assigned the variable the correct value. To prove it, evaluate the variable somewhere below by typing "v.op1_out="

Example:

Note, that Mathcad's symbolics does not know anything about units and Ohm and kOhm are treated as two different variables.

Evaluating the variable numerically gets things sorted out.
