The importance of mastering knowledge of electronics

Grasp some relevant knowledge of electronics is indispensable, such as the maintenance of a hardware in the multimeter to measure a resistance value is infinite, while can be concluded that the resistance is damaged, but as a result of each board and various kinds of computer peripherals are no circuit diagram, therefore, and do not know resistance without damage when specific resistance, so they can't to change new the damaged components.

But if you can understand the color on the resistance ring logo, you then know that this may have damaged the nominal value of the resistance, change new also won't be a problem, the fault also will come out naturally. Such as the above situation still has a lot of, such as components of the right to choose.
