Ohm's Law | Statement, Derivation, Its Applications And Limitations Ohm's Law Why The Temperature Is Kept Constant In Ohm’s Law Applications of Ohm’s Law Limitations of Ohm’s Law: Ohm's Law: Ohm's Law states, that current through any conductor is directly proportional to the potential difference between its two ends, Temperature, and other physical quantities being constant Potential difference ∝ Current &nbsp &nbsp &nbsp &nbsp &nbsp V ∝ I ( When the value of V increases the value of I increases simultaneously) &nbsp &nbsp &nbsp &nbsp &nbsp V = IR where, V is Voltage in volts (V) I is Current in Ampere (A) R is Resistance in ohm (Ω) Why The Temperature Is Kept Constant In Ohm’s law: The main criteria for Ohm’s law is to keep the resistance constant because proportionality constant in the relationship is resistance R. But we know that the variation of tempe

Faraday's Law Of Electromagnetic Induction And Its Applications What Is Electromagnetic Induction Faraday's Law Of Electromagnetic Induction Lenz’s law of Electromagnetic Induction Applications of Electromagnetic Induction What Is Electromagnetic Induction Electromagnetic Induction or Induction is a process in which a conductor is put in a particular position and magnetic field keeps varying or magnetic field is stationary and a conductor is moving. This produces a Voltage or EMF (Electromotive Force) across the electrical conductor. Michael Faraday discovered Law of Induction in 1830. Let us now study the Electromagnetic Induction in detail. Faraday's Law Of Electromagnetic Induction First law: Whenever a conductor is placed in a varying magnetic field, EMF induces and this emf is called an induced emf and if the conductor is a closed circuit than the induced current flows through it. Second Law: The magnitu
