Make the LED bulb light with one wire and a battery.

NOTE: Do not leave your LED connected to your battery for long. LEDs usually need to be in circuits with resistors to ensure the bulbs don't blow. You will learn about this in more detail in later lessons.


Please answer the questions below.

Draw the orientation that made the light bulb light in challenge 5.
