Some – will be able to recognise and create real world examples. What is a transistor? Transistors are tiny electronic switches and amplifiers. Several thousand transistors can be put on a piece of silicon with a surface area of just 1 mm 2. Transistors have three main uses: – as an electronic switch within a circuit – to switch on another part of a circuit when a change in resistance of a sensor device is detected – as an interface device, to receive signals from low current devices (such as ICs) and use these to turn on high current devices (such as motors)
