Simulating time variable resistors - Simulate time variable resistors in LTSPICE using a voltage source as controller

LTSPICE allows control of the resistance of a standard resistor element by a voltage source. This can be used to set up the time variable resistance of a resistor by creating an equivalent time variable voltage source.

To do this, set up a voltage source and label the voltage source's output net with a descriptive name (e.g. Vresistance). In the value field of the time variable resistor set the value to R=V(Vresistance). Set up the voltage to represent the time variable behavior as...
