  2. Supply electrical energy
  3. Control the flow of currentالإجابة الصحيحة
  4. Convert electrical energy into radio waves

الشرح

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.
