A student is building a circuit with a battery, a switch, and an LED. They notice that the LED is very bright and might be damaged. What component should they add to the circuit to protect the LED?
Another battery.
A larger switch.
A resistor.
Another LED.
Imagine you have a flashlight with a battery and a bulb. When you turn on the flashlight, the battery sends an electric current that makes the bulb light up. Now, imagine that inside the flashlight there is a small obstacle that makes it difficult for this current to pass. If this obstacle gets bigger, what do you think will happen to the brightness of the bulb?
The bulb will keep shining just as bright.
The bulb will shine less.
The bulb will shine brighter.
The battery will drain faster.
