What happens to the amplitude of the induced emf when the rate of rotation of a coil is doubled? (a) It becomes 4 times larger (b) It becomes 2 times larger (c) It is unchanged (d) It becomes one half as large (e) It becomes one fourth as large

Step 1
Step 1: The formula for induced EMF is given by \(E = B \cdot A \cdot \omega\), where \(B\) is the magnetic field, \(A\) is the area of the coil, and \(\omega\) is the angular velocity of rotation. Show more…

What happens to the output voltage amplitude and frequency when a generator's rotational speed is decreased? (A) The amplitude and frequency stay the same. (B) The amplitude and frequency decrease. (C) The amplitude stays the same, but the frequency decreases. (D) The amplitude decreases, but the frequency stays the same.

(a) coil? (b) What if? Which would lead to a larger peak emf in the second coil, a doubling of the mutual inductance or a doubling of the frequency with which the current in the first coil changes? Doubling the mutual inductance would lead to a larger peak emf. Doubling the frequency with which the current in the first coil changes would lead to a larger peak emf. The two changes would each have the same effect.
