This is a common problem that involves the basic principle of resistors and the flow pattern of current.

The resistor commonly used in circuits is an electronic component used to limit the flow of current.

Resistors are one of the common components in circuits, and their role is very important.

A resistor is a common electronic component used to control the resistance value in a circuit.

Sensitive resistor refers to a resistor whose device characteristics are sensitive to temperature

By evaporating a certain resistivity material onto the surface of the insulating material, it is made.

A potentiometer is an electromechanical component that relies on the sliding of a brush on a resistor to obtain an output voltage that is proportional to the displacement of the brush.

Direct marking method: Use numbers and unit symbols to mark the resistance value on the surface of the resistor
