  • ELECTO-MAGNETIC INDUCTION

    ELECTO-MAGNETIC INDUCTION 1. Electro-Magnetic Induction:- The phenomenon of electro magnetic induction is simply the production of electricity by a changing magnetic field associated with an electric circuit containing no source. 2. Faraday’s law of Electro-Magnetic Induction:- The Faraday’s law of electro magnetic induction states that the induced e.m.f in a closed circuit (coil) is equal […]

  • RESISTANCES IN SERIES AND PARALLEL

    RESISTANCES IN SERIES AND PARALLEL 1. Resistances in Series:- In a circuit, resistors connected end-to-end are said to be in series, if the same current exists in all of them through a single path. Note:- When resistors are connected in series 1. The same current passes through all of them 2. The voltage of the […]

  • LAWS OF RESISTANCE

    LAWS OF RESISTANCE 1. On what factors does the resistance of a conductor depend The resistance of a conductor depends on material, dimensions such as length area of cross-section and temperature. 2. Laws of Resistance:- Laws of Resistance are:- The Resistance ‘R’ of a conductor of a given material is directly proportional to its length […]
