What is the function of component 2 in figure T-1?
Give off light when current flows through it
Supply electrical energy
Control the flow of current✓Ճիշտ պատասխան
Convert electrical energy into radio waves
Բացատրություն
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.
