Laws of electromagnetic induction: Electro-magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. So, the process of creating electromotive force and current in a closed coil…

Cycle of variation: The process of changing the alternating electromotive force or current starting from zero to a maximum value, then decreasing to zero and then again increases in the reverse direction and reaches the…

Amplitude: The maximum value of the electromotive force or current in any direction is called amplitude. Amplitude is the utmost value of current or voltage. It is represented by either of the two peaks of…

Current A flow of charge is called current. But in general meaning, a flow of electrons is current. Electrons remain outside the nucleus and protons remain inside the nucleus. It is easier to flow electrons,…

Primary and Secondary Coil: Current-carrying cod is called primary coil and the coil in which induced current is generated is called secondary coil. An alternating current flows in the primary coil and this induces a…

Induced Electromotive Energy: Electromotive energy generated in a closed circuit clue to electromagnetic induction is called induced electromotive induction. It is the electrical strength or “pressure” developed by a source of electrical energy such as…

Induced current: Current generated in a closed circuit due to electromagnetic inductions is called induced current. It is a current due to variation in the magnetic field surrounding its conductor. It is an electric current…

Explanation on Generation of alternating current There is a source of current from which the flow of current in the circuit changes direction spontaneously at a regular interval. This current is called alternating current. Alternating…

Alternating current There is a source of current from which the flow of current in the circuit changes direction spontaneously at a regular interval. This current is called alternating current (Figure). Alternating current describes the…

Direct current: We know that the current we get from a battery or an electric cell flows always in one direction. This flow is called uni-directional or direct current. It is the unidirectional flow or…
