Variable Conductor

Ideal linear electrical conductor with variable conductance

 Description The Variable Conductor component models a variable, linear electrical conductor with an optional heat port and temperature dependency. The conductance is allowed to be positive, zero, or negative.
 Equations $i={i}_{p}=-{i}_{n}={G}_{\mathrm{actual}}v$ $v={v}_{p}-{v}_{n}$ ${G}_{\mathrm{actual}}=\frac{G}{1+\mathrm{\alpha }\left({T}_{\mathrm{res}}-{T}_{\mathrm{ref}}\right)}$ ${T}_{\mathrm{res}}=\left\{\begin{array}{cc}{T}_{\mathrm{heatPort}}& \mathrm{Use Heat Port}\\ T& \mathrm{otherwise}\end{array}$ $\mathrm{LossPower}=vi$
