Classroom Ideas

Could be used to support exam revision into transistors and Darlington pairs when used as current amplifiers. Pupils could watch the video and make notes to aid their revision. The teacher could show each separate section about transistors and Darlington pairs, and ask questions after each to check pupil understanding. Pupils could also use this as part of their project work to support them when selecting the appropriate current driver for their circuits.
