Transistors are 1. electronic components. Their two main types are 2. and FET. The first type of transistors can have PNP or 3. configuration. They are made of three components: 4. , base and 5. . On the other hand, FETs are made of these three components: 6. , 7. and drain. The basic functions of transistors are to work as a 8. , blocking or unblocking current, or as an 9. , making current bigger.
8. Read the sentences and decide which type of transistor they refer to.
1. It can be either PNP or NPN. 2. A voltage applied to its gate creates a field effect. 3. Its base is connected to a circuit providing current. 4. It is coated with metal oxide. 5. Its gate can be opened or closed. 6. It is more suitable to be used as a switch. 7. Its emitter and collector are connected to an output circuit. 8. It is more suitable to be used to amplify current.
