Question 258

What is the function of component 2 in figure T-1?

Figure T-1 from the official question pool: a schematic diagram of a small electronic circuit with parts numbered 1 through 5.
  1. Give off light when current flows through it
  2. Supply electrical energy
  3. Control the flow of currentCorrect answer
  4. Convert electrical energy into radio waves

Explanation

Component 2 is the NPN transistor, whose function in Figure T-1 is to control current flow. Component 3 is the lamp that gives off light and component 4 is the battery that supplies energy; the remaining choice does not describe the transistor's current-control role.
