Questions:
1) What is the resistance if you run 10 volts and 5 amps on a circuit?
2) Explain why the cross sectional area is important when determining the materials resistivity.
3) Explain why the voltage and resistance will change depending on the length of the material.
4) What happens to the resistor as the current is left running for a long period of time? What will the results of the experiment be if you did leave the current running?
