A student is investigating a resistance wire. She measures the current in a $50\,\text{cm}$ section of resistance wire. The student then repeats the experiment with a $100\,\text{cm}$ section of the same resistance wire. What effect does this change have on the current in the circuit and on the wire’s resistance?
- Acurrent decreases; resistance decreases
- Bcurrent decreases; resistance increases
- Ccurrent increases; resistance decreases
- Dcurrent increases; resistance increases
