Ohm S Law Experiment Class 10

Cbse class 10 science lab manual ohm s law aim to study the dependence of potential difference v across a resistor on the current i passing through it and determine its resistance r.

Ohm s law experiment class 10. Ohm s law states that at a constant temperature current i through a conductor between two points is directly proportional to the potential difference or voltage v across the two points that is. The negative charge is due to electron. There are two charges in nature i e positive and negative. Question 2 what is the resistance of an electric arc lamp if the lamp uses 20 a when connected to a 220 volt line.

One coulomb is the amount of charge present on 6 25 x 10 18 electrons. I hope you have liked this post on the law of ohm. Introducing the constant of proportionality the resistance one arrives at the usual mathematical equation that describes this relationship.
