materials easily. Resistors can be fabricated in a variety of ways. The most common type in electronic devices and systems is the carbon-composition resistor.

The amount of resistance offered by a resistor is determined by its physical construction [8].

For example, gold, silver, and copper have low resistance, which means that current can flow easily through these materials.

Glass, plastics, and wood have very high resistance, which means that current can not pass through these

Resistance can be written in a number of different ways depending on the ohm rating. For example, 81R represents 81 ohms, while 81K represent 81,000 ohms. The resistance varies in different materials [3]. [3].不同物体的阻抗不同。 vary in … 依据…而变化 。
