Example implementation:
  • user is provided with a "variable editor" where he inputs an new variable "ReferenceResistor=500"
  • user edits his circuit and make R1, R2, R3 and R4's resistance = ReferenceResistor and R10 and R11 = ReferenceResistor 2*ReferenceResistor
This way user is able to change quickly/test various values
