Equation (1) is a result of Faraday's law of induction and this is the reason transformers work only with AC. A transformers is called a "voltage step-up transformers" if the secondary voltage Vs is greater than the primary voltage Vp.
Section-A
vaga.study11. On what effect of an electric current does an electromagnet work? [1] Ans : An electromagnet works on the principle of magnetic effect of current. 12. State Faraday’s law of electromagnetic induction. [1] Ans : Whenever the magnetic field lines linked with a coil change due to relative motion of a magnet and the
