Diodo

Diodes are electronic components that allow current to flow in one direction. They are used in various applications, such as converting alternating current (AC) to direct current (DC) and creating audio signals from high-frequency radio signals. Modern diodes are typically semiconductor devices, which are smaller and more cost-effective than the original vacuum tubes, now primarily used for high-current applications.

What is the primary function of a diode?

• To convert light into electricity

• To amplify signals

• To conduct current in one direction

• To store electrical energy

In which application are diodes used to convert AC to DC?

• Light emission
