Which of the following devices is based on the principle of Faraday’s law of electromagnetic induction ?
The transformer works on the principle of Faraday's law of electromagnetic induction, which states that a change in magnetic flux through a coil induces an electromotive force (EMF) in the coil. In a transformer, an alternating current (AC) in the primary coil generates a changing magnetic field, which induces a voltage in the secondary coil, allowing for voltage transformation.
