Question
The maximum induced emf in a generator rotating at $22 \mathrm{rad} / \mathrm{s}$ is $45 \mathrm{~V}$. How fast must the rotor of the generator rotate if it is to generate a maximum induced emf of $55 \mathrm{~V}$ ?
Step 1
Step 1: The maximum induced emf in a generator is given by the formula $E = NAB\omega$, where $N$ is the number of turns, $A$ is the area of the coil, $B$ is the magnetic field, and $\omega$ is the angular speed. Show more…
