NAICS 334415 applies to Electronic Resistor Manufacturing.
The symbol for a rheostat is a resistor with an arrow indicating a variable resistance that can be adjusted by a knob or slider. It is commonly used in electronic circuits to control the flow of current.
The symbol for Light-Dependent Resistor (LDR) is a resistor symbol with photo-sensitive material added to one side. It looks like a regular resistor with one side having a shaded area to represent its light sensitivity.
The symbol of a thermistor is a resistor with an arrow pointing towards it.
The resistor with an arrow through it in electronic circuits represents a variable resistor, also known as a potentiometer. It is significant because it allows for the adjustment of resistance in the circuit, which can control things like volume, brightness, or speed in electronic devices.

Variable resistor is an resistor that can change its resistance manually, by rotating a handle or a screw.
Equivalent Resistor
Put the resistor symbol ie zig zag. Then put a crossing line with arrow headed at the top.

electronic circuits are those which deals with flow of electrons. in general electronic devices are categorized based on the flow of e as conductor, insulator and semiconductor. since resistor resists the flow of electrons (it deals or works with electrons), it is consider as an electronic device.
