This practical resource introduces applications of transistors and basic transducer devices and some of their typical configurations. 

Practical tasks include the following:

• Identify the symbol, construction, and operating characteristics of an LDR and a thermistor
• Investigate the operation of an LDR
• Investigate the operation of a thermistor
• Identify the operation of a simple transistor switch circuit
• Recognize how a Darlington pair improves the sensitivity of a switching circuit
• Troubleshoot a single transistor switch circuit
• Troubleshoot a Darlington pair light-level alarm circuit
• Identify the difference in operation between single transistor and Darlington pair emitter follower circuits
• Investigate a Darlington pair emitter follower
• Troubleshoot a Darlington pair emitter follower circuit
