What is Ohm\'s LawDiscribe about it? |
|
Answer» At any constant temperature the current flowing through a conductor is directly perpotional to the potential difference accross the conductor. Ohm’s LawGeorge Simon ohm(in 1826)studied relationship between I and V across the ends of conductor.Ohm’s Law\xa0states that electric current flowing in a conductor is directly proportional to potential difference across the ends of the conductor,provided temperature and other physical conditions remains constant.V=IRR=Resistance of conductorResistance of a conductor is the property of conductor to oppose the flow of charge through it.R = V/IUnit of resistance is ohm1 ohm = 1 Volt\xa0/\xa01 AmpereResistance of a conductor is said to be 1 ohm if a potential difference of 1 volts across the ends of conductor makes a current of 1 ampere to flow through it.Slope = I / VSlope of graph V and I=Resistance of a conductorV=IRI= V/RIf R is halved then I is doubled.If R is doubled then I is halved. |
