Diodes and Transistors

How these simple semiconductor devices allow us to control the strength and flow of electrical current in a circuit, and are integral components in modern electrical equipment. Physics - Electricity And Circuits - Learning Points. Transistors and diodes are semiconductor devices. Diodes conduct electrical current in only one direction. Transistors boost signals and make excellent amplifiers. A single computer chip contains millions of diodes and transistors. A Twig Curriculum Film. Delivering key learning points.
