Los diodos y los transistores

The video explains the role of diodes and transistors in electronics. Diodes, made from semiconductors, allow current to flow in one direction and are used in various applications like battery protection and AC to DC conversion. LEDs, a type of diode, emit light and are used in screens. Transistors, with three layers, control current flow and amplify signals, playing a crucial role in devices like radios. Both components are integral to modern electronics, enabling miniaturization and technological advancements.

What is the primary function of a diode in an electrical circuit?

• To allow current to flow in one direction only

• To convert electrical energy into light

• To amplify electrical signals

• To store electrical energy

How do diodes protect battery-powered devices?

• By amplifying the current

• By blocking current if batteries are inserted incorrectly

• By emitting light

• By converting AC to DC

Which type of diode is used to produce light in devices like TV screens?

• Schottky diode

• Photodiode

• Zener diode

• Light-emitting diode (LED)

What distinguishes a transistor from a diode in terms of structure?

• A transistor has two layers, while a diode has three

• A diode has more layers than a transistor

• A transistor has three layers, while a diode has two

• Both have the same number of layers

What was one of the first applications of transistors in the mid-20th century?

• Transistor radios

• Computer chips

• Television screens

• LED lights
