length of a conducter is increased by 20%. what will be the effect on resistance and resistivity? someone please give me brief description I don't know anything about this topic

rekhapilania: di!please give brief description

haniya70: mark me as brainliest

rekhapilania: I will but please give me brief description of this type of questions

haniya70: thank you dear so much

haniya70: I can help u

rekhapilania: please

haniya70: u know about current

rekhapilania: yes

haniya70: It is actually the formulas u have learn

rekhapilania: I know but there also a question that is the length of a conducter increased to 120% then what will be effect on resistance and resistivity

Answered by haniya70

resistivity is equal to Rho× length/ Area of cross section .So if length is increased so resistivity will also increase same can be happen for resistance....

haniya70: lt from the topic electricity. In this topic u have know that What is current, voltage, resistance, resistivity,conductance, conductivity
