The component represents an electrical resistance. Within the dialog you can choose a linear
or nonlinear resistor type.
Dialog Settings
� «Resistance [Ohm]»
The Linear Resistor is selected. Common parameter type. Enter a numerical value, a variable,
or an expression in the text box or use the pin to connect a quantity.
� � «Use pin»
If the box is checked, the resistance is defined by the quantity connected to the pin, otherwise
the value in the text box is used.
� «Nonlinear i=f(v)»
The Nonlinear Resistor is selected. Open the characteristic dialog or use the pin to define a
characteristic. See also “Separate Component Characteristic” on page 297.
� � «Use pin»
If the box is checked, theresistor is defined by the characteristic connected to the pin, otherwise
by the settings in the dialog .
Linear Resistor
vt () =
R⋅i() t
The resistance is equivalent to the present value of the quantity specified in the text box. For
the quantity any numerical value, variable, mathematical or logical expression can be used.
Usually a Constant value, a Time function, or a variable are chosen, or the value of the resistance
is determined in a state graph. A mathematical expression must conform to the syntax
of the SIMPLORER expression interpreter. All system quantities and variables can be combined
with mathematical and logical operators and constants.
However, the expression must be technically meaningful. If it is not, numerical instability or
completely wrong results are possible. In particular, sudden changes in the first derivation of
the control quantity should be avoided.
