In an AC generator, a coil with N turns, all of them has same area A and total resistance R, rotates with an angular frequency ω in a magnetic field B. The peak value of current in the coil is-
AC generator works on the principle of Faraday's law of electromagnetic induction, which states that if the flux associated with a conducting coil changes, an induced emf is produced in the coil, and if the coil is closed, a current flows through the coil. |
