Variable Resistor with Constant Capacitor
Purpose
Variable resistor with constant parallel capacitor.
Library
Electrical / Passive Components
Description
This component models a variable resistor with a constant capacitor connected in
parallel. The resistance is determined by the signal fed into the input of the
component. It may not be set to zero.
Parameters
-
Capacitance
- The value of the capacitor, in farads (F). All finite positive and
negative values are accepted, excluding 0. The default is 100e-6.
In a vectorized component, all internal capacitors have the same value if
the parameter is a scalar. To specify the capacitances individually use a vector
. The length
of the vector determines the width of the
component.
-
Initial voltage
- The initial voltage of the capacitor at simulation start, in volts
(V). This parameter may either be a scalar or a vector corresponding to the
width of the component. The positive pole is marked with a "+". The initial
voltage default is 0.
Probe Signals
-
Capacitor voltage
- The voltage measured across the capacitor, in volts (V). A
positive voltage is measured when the potential at the terminal marked with
"+" is greater than the potential at the unmarked terminal.
