VariableResistor

Ideal linear electrical resistor with variable resistance

    VariableResistor

Library

Modelica/Electrical/Analog/Basic

Description

The linear resistor connects the branch voltage v with the branch current i by
i*R = v
The Resistance R is given as input signal.

Attention!!!
It is recommended that the R signal should not cross the zero value. Otherwise depending on the surrounding circuit the probability of singularities is high.
