Question 22
F

A student measures the resistance of a length of nichrome wire at constant temperature. The wire is then cut to half its original length. What happens to the resistance, and to the current for the same potential difference?

[1]
A

The resistance halves and the current in the wire also halves

B

The resistance halves and the current in the wire is doubled

C

The resistance doubles and the current in the wire is halved

D

The resistance doubles and the current in the wire is doubled
