The graphic symbol of resistor

In applying actually, the type of resistor is varied, corresponding graphic symbol also is distinguished somewhat, accordingly, understand the graphic symbol of the resistor of different type, the type of the resistor in giving electronic circuit to pursue to accurate identifying has important sense.
The graphic symbol of common resistor, appearance and function pursue as follows:

Resistor is divided normally in the label in electronic circuit for two parts, one part is graphic symbol, the type of label resistor; Another part is a letter + number, label this resistor reachs main parameter in the name in circuit, serial number.
