1. The problem statement, all variables and given/known data A student is calculating the resistance of a piece of fuse wire. He takes 5 readings on the voltmeter and ammeter for different settings of a variable resistor. He wants to avoid heating effects in the wire. How would he do this? 2. Relevant equations V=IR 3. The attempt at a solution 1. Have a fan blowing at the circuit. 2. Have an air conditioning machine near by. 3. If the middle part of the wire is covered in plastic insulation then place that part of the wire in a tub of room temperature water. I thought about a tub of ice but that may be too cold? This is High School physics. Thank you.
