How to calculate Resistivity and resistance

How to calculate factors affecting the resistance of a material
This explains how to calculate factors affecting the resistance of a material, length, area, resistivity and temparature. It provides the formula to calculate the resistance of a metal or wire using resistivity. It discusses the inverse relationship between resistance and area , the direct relationship between resistance and length, as well as resistance and temperature. Electrical conductors such as metals have a positive temperature coefficient of resistivity which means as the temperature increase so will the resistance of a conductor. For metalloids, the opposite is true. These elements have a negative temperature coefficient, which means as my temperature increase my resistance will decrease. The resistivity depends on the length, cross-sectional area and temperature of a conductor. This video shows examples of how to manipulate the standard formula to calculate length, area, resistivity and resistance. It also shows how to calculate temperature.

this is so great i learnt a lot from this i hope this will help me well in my physics exams THANK YOU SO MUCH

[@normanchristians6325]

Very good explanation with easy to follow graphics...awesome stuff!!!

[@digitalschool101]

Thank you.

[@ferdinandwilhelm8749]

Fantastic video. Thank you!

[@morgangishali9088]

The work is perfectly fine but please u should show us every stage how u are changing Every unit e.g like 1km to 100m or 1*10-3=?... All in all we are benefiting from yo work we are beginners thanks

[@AndreasIdam]

So good!!! Way better explained than in my apprenticeship

[@digitalschool101]

Thank you

the T is ( T final - T initial ) still works but since the initial is zero so he can jump on 65 right away

Thank you 🙏🏾

On example 4 should you time the resistivity by 10 to the minus 8 ?

[@janetbinyotubo3292]

Why did you not use the pi while finding d area

[@aaunitenewzealand2133]

Wrong answer in example 4
