Trimmer Resistor Schematic Symbol. This symbol represents a microcontroller s i o pin functioning as both and input and output in a circuit. Rheostat it is a two terminal variable resistor.
Component symbol component symbol. They react the same way and when a voltage or current ac or dc is applied a constant output is observed e g. It is also called trimmer.
This symbol represents a microcontroller s i o pin functioning as both and input and output in a circuit.
In circuit diagrams the symbol for a variable component is the symbol for a. Bulb indicator lamp resistor. Resistor symbols of electrical electronic circuit diagram resistor potentiometer variable resistor. When they are used as a variable resistance wired as a rheostat they are called preset resistors.
