Answer 1

This results in current flowing through the copper wire and the bulb lights up.

Explanation:

• When a sufficient amount of salt is added to water, salt water is formed.
• Saltwater can generate electricity as it serves as an electrolyte.
• When salt is added to distilled water and graphite rods are added in it then the charges begin to flow.
• The current flows through the copper wire and reaches the battery and the bulb lights up.
