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. #factorseffectingtheresistanceofaconductor #resistivity #resistance #temperaturecoefficient #positvetemperaturecoefficient #negativetemperaturecoefficient #length #area Like and subscribe to my channel and don't forget to click on the notification bell👍 https://www.youtube.com/channel/UCqFU...
