ohms law class 10
OHM’S LAW OHMS LAW:-- Ohms law provides relationship between the potential difference and current flowing through the metallic conductor in a circuit. Ohms law states that , at a constant temperature , there is relationship between the current carrying conductor (I) , flowing through the metallic wire or conductor and potential difference (V) is crossing through its terminal. Now, in an electric circuit, the potential difference (V) , across the ends of the metallic wire is directly proportional to the current flowing through it. This is called ohms law. Mathematically , this law can be expressed as follows:-- V ∝ I Or , I ∝ V V/I = constant V/I = R Here R is the resistant. SI unit of R is (Ω) (Ω) :-- Its represented by Greek letter. And also called as omega According to ohms law, R = V/I 1 OHMS is expressed as if the potential difference (PD) of a conductor is 1V and the current passing through
