A student is carrying out an investigation into a resistance wire. She measures the current in a $50\,\text{cm}$ piece of resistance wire. The student then repeats the experiment with a $100\,\text{cm}$ piece of the same resistance wire. How does this change affect the current in the circuit and the resistance of the wire?
- Acurrent decreases; resistance decreases
- Bcurrent decreases; resistance increases
- Ccurrent increases; resistance decreases
- Dcurrent increases; resistance increases
