Question 1

Under lying chemistry part 1

Answer 1

To make voltage you need an electrolyte to allow electrons to move. Electrolyte is when a solution can conduct electricity due to the ions in the solution. The salt soaked filter paper used on the simple cell experiment below is an ion bridge, the purpose of this is to let the ions flow which helps to finding the circuit

Question 2

Underlying biology part 2

Answer 2
