DC Generators: Producing DC Voltage (VCE SSCE Physics): Flashcards

Kinetic (mechanical) energy to electrical energy

Electromagnetic induction

$\Phi_B = AB \sin \theta$

$\varepsilon = -\frac{d\Phi_B}{dt}$

Zero (flux is momentarily constant)

Converts AC in coil to DC in external circuit

Provide electrical connection between coil and external circuit

Produces smoother, more constant DC output

Stronger fields, self-excitation, field control

When flux is zero and changing most rapidly
