Online tutorial on how to find resistance and resistivity of a conductor

The purpose of this video is to illustrate the steps required in calculating the resistance of a given conductor.
The resistance of any given conductor is dependent upon four factors.
1. Temperature: Resistance varies with the temperature of the conductor. Resistance increases as the temperature of the conductor rises.
2. Type of material: The type of material from which the conductor is made also contributes to its overall resistance.
3. Length of the conductor: The length of the conductor is directly proportional to its resistance.
4. Cross-sectional area of the conductor: The cross sectional area of the conductor is inversely proportional to its resistance.
Hence we can say that, with increase in length of the conductor, its resistance increases. However, as we increase cross-sectional area, the conductor's resistance decreases.
Resistivity is used to compare the inherent resistance characteristics of a material.
The resistance of a given conductor is equal to the material resistivity times the ratio of length to cross-sectional area. The relationship is given as under,
Resistance = Resistivity x ( Length / Area )
The video illustrates this relationship using a simple example of a gold conductor. More circuit troubleshooting is performed using simulation tool such as circuit logix which is provided free with Electronics and Electromechanical technician programs offered by George Brown College.

Sorry, I did not mean to complicate things, I have a lot of students with dimension conversion issues, so I needed to add that stuff in there. I hope you found it helpful though.

Great tutorial. However, once I had all of the values ready for the final equation I was lost, it would be great if you had continued right to the answer. Thanks

u could have used a more simpler example but thank you!
