Question:
How does the thickness of a wire affect the electrical current?

Replies:
Consider water. Compare the amount of water you can get through a straw and through a sewer pipe. The straw will offer more resistance. Here is an activity you can do: Try blowing through one straw. Then try blowing through two side by side straws; then three, etc. You will notice the resistance reduce.
