Step 1
Step 2
Answer
If the terminals of the battery are reversed, the LED would not light. This is due to the fact that LEDs are polarized components, meaning they only allow current to flow in one direction. Reversing the battery terminals reverses the current flow, preventing the LED from functioning.
