1.10. Applications

Try these first

1. 1.

   What does a diode do?

   Hint

   Think about how water flows in a pipe.

2. 2.

   What type of charge carriers do BJTs use?

   Hint

   Consider the terms 'bipolar' and 'junction'.

3. 3.

   What is the main function of a diode?

   • Allows current in both directions
   • Allow current in one direction
   • Converts light to electricity

   Hint

   Think about where you might see diodes used.

4. 4.

   True or False: BJTs use only one type of charge carrier.

   • True
   • False

   Hint

   Consider the meaning of 'bipolar'.

5. 5.

   Design a simple circuit using a diode and a power source to demonstrate rectification.

   Hint

   Think about how directionality of current flow affects the load.

6. 6.

   Analyze the efficiency factors of a solar panel and suggest improvements.

   Hint

   Consider how sunlight interacts optimally with materials.
