• 6. What does the current through an electrical circuit depend on?
• The potential difference provided by cells connected in series is the sum of the potential difference of each cell (depending on the direction in which they are connected).
• 7. What is mains electricity and how can it be used safely?
• Cells and batteries supply current which always passes in the same direction. This is called direct current (d.c.).
