Resistor
Linear resistor.
Description
The Resistor block represents a linear resistor described by the following equation:
where:
-
- voltage;
-
- current;
-
- resistance.
The + and - connections represent the electrical ports corresponding to the positive and negative terminals of the resistor, respectively. By convention, the voltage across the resistor is defined as , and the sign of the current is assumed to be positive as it flows through the device from the positive to the negative terminal. This convention ensures that the power drawn by the resistor is always positive.
Ports
+ - positive
