Faraday’s law of Induction – Statement, formula

Scientist Oersted observed that a current carrying wire produces magnetic field around it. One can find the magnitude of the magnetic field by using Biot-Savart law and Ampere’s circuital law. The direction of the magnetic field can be found by using Fleming’s right hand Thumb rule and Maxwell’s corkscrew rule. Have you ever wondered if … Read more

Working Principle and Formula of a Transformer

Electricity Transformer is an electrical component that transforms the alternating electric power from one circuit to another circuit with the same frequency of the signal. It can change the amplitude of alternating voltage to a desired value at the output. But the power remains the same both at the primary and secondary coil. In this … Read more
