Pick an answer to check it.
Answer: C. Control the flow of current
Component 2 in Figure T-1 is a transistor. In this circuit, a small signal at its base controls the larger current through the lamp, so its job is to control the flow of current. The lamp gives off light and the battery supplies energy.
Tip: The transistor is the circuit's controller.
