Resistance of a wire

Resistance of a wire
Publication Date: January, 2015
Type of Resource: Practical activity/investigation

These downloadable resources are for a student practical activity focusing on the factors that determine a wire's resistance.

The independent variables of length and cross-sectional area are investigated for nichrome wire. Graphs can be drawn to confirm the relationship of these variables to the resistance. The concept of resistivity is introduced and explained. 

Sample answers are provided along with a sample Excel spreadsheet of data tables and graphs.
