Chapter 4, Problem 47E

Explanation of Solution

Construction of transistor:

• A transistor is made up of a semiconductor material like silicon.
• The behavior of a semiconductor material is that it neither acts as a good conductor of electricity nor a good insulator.
• A transistor is a device that behaves like a wire or a resistor depending upon the voltage level of the input signal.
  • If a transistor plays the role of a wire, it conducts electricity.
  • If a transistor plays the role of a resistor, it blocks the flow of electricity.
• Transistor has no moving parts; but can act as a switch...
