A diode is a two-terminal electronic component that allows current to flow in one direction only. It exhibits low resistance in the forward direction and high resistance in the reverse direction. This property makes diodes useful for controlling the direction of current flow in electronic circuits.

What is true about diodes?

Lots of things are true about diodes. There are different types of diodes; their general characteristic is that they have two electrodes (electrical contacts). They conduct current in one direction only.


Which of these ststements is true of diodes?

Diodes allow current to flow in one direction and block it in the other, acting as a one-way valve for electrical current. They have a forward voltage drop when conducting in the forward direction and can be used in various electronic applications to control current flow.


What are the intrinsic and extrinsic diodes?

Intrinsic diodes are formed by a p-n junction within a single semiconductor material, while extrinsic diodes are formed when impurities are added to a semiconductor material to alter its properties. Intrinsic diodes have natural electrical properties, while extrinsic diodes have controlled electrical properties based on the type and amount of impurities added.


Why would you use silicon diodes instead of germanium?

Though germanium diodes were the first ones fabricated, several factors make silicon the choice vs. germanium diodes. Silicon diodes have a greater ease of processing, lower cost, greater power handling, less leakage and more stable temperature characteristics than germanium diodes. Germanium diodes' lower forward drop (.2V to .3V versus .7V to 1.0V) make them better at small signal detection and rectification.
