How can I use a resistor value to compute an expression? SOLVED


I'd like to compute expressions using the values of resistors. For example: V(node1) = I(R1.nB) * R1 How can I make reference to the value of R1? Is it possible? Thanks

Sorry but parameters are not supported in CL yet.

You might like to add you voice to the Feature Request for that here:

A very clumsy workaround is to use voltage (or current) sources to define values or variables and then reference the voltages in the expressions.

However, in your case you would then have to use a behavioural resistor in order to be able to use the voltage to set the value of the resistor!

Examples of behavioural resistors:

and of using voltage sources to set parameters:

Thank you!

"How can I make reference to the value of R1?"

This is now supported with R1.R, right?
