ohm•m answer
1. What is the resistance of one of the wires, how much current will it carry if a voltage of 9 V is applied to it, and how much power will that be?
2. How would you connect these wires to make the largest possible resistance while still carrying current, and how much power would that be if 9 V were applied?
3. How would you connect these wires to make the least possible resistance, and how much power would that be if 9 V were applied?
4. If you had two 9 V batteries and four of these very fine wires, how would you use them to generate the most loss in power in the wires? That would be the most heating while
current is flowing, though the actual energy delivered in total is determined by the energy stored in the batteries.
