Description

Block Resistor It is a linear resistor described by the following equation:

where

  • — tension;

  • — current;

  • — resistance.

The + and − connections are electrical ports corresponding to the positive and negative terminals of the resistor, respectively. The voltage across the resistor is defined as , and the current sign is assumed to be positive when flowing through the device from the positive to the negative terminal. This ensures that the power consumed by the resistor is always positive.

Variables

Use the parameter group Initial Targets to set the priority and initial target values for the block parameter variables before modeling. For more information, see Configuring physical blocks using target values.
