Electromagnetic induction & Faraday’s law of induced EMF

Scientist Oersted first observed that a current carrying wire produces magnetic field around it. One can find the magnitude of this magnetic field by using Biot-Savart law and Ampere’s circuital law. Again, the direction of this magnetic field is given by Fleming’s right hand Thumb rule and Maxwell’s corkscrew rule. Now, the question is that … Read more

Transformer formula of Step up & Step down transformer

Transformer is an electrical component which transfers the alternating electric power from one circuit to another circuit keeping the frequency of signal same. It can change the amplitude of alternating voltage to our desired value at the output. But the power remains same both at primary and secondary coil. In this article, we am going … Read more
