Due to the infrared light-emitting diode, it emits infrared light of 1-3 μ m
The positive and negative poles of a crystal diode can be distinguished according to the following methods
The positive and negative poles of a crystal diode can be distinguished according to the following methods:
Use batteries and speakers to distinguish the positive and negative terminals of diodes,
The main characteristic of a diode is its unidirectional conductivity, and its volt ampere characteristic curve
Due to the presence of junction capacitance, when the frequency reaches a certain level,
