Electrodynamics Flashcards
1
Q
Magnetic Flux Linkage
A
The product of the number of turns on the coil and the flux through the coil (NФ)
2
Q
Faraday’s law of electromagnetic induction
A
the emf induced is directly proportional to the rate of change of magnetic flux (flux linkage)
3
Q
Lenz’s Law
A
the induced current flows in a direction so as to set up a magnetic field to oppose the change in magnetic flux
4
Q
Motors convert
A
electrical energy to mechanical energy
5
Q
Generators convert
A
mechanical energy to electrical energy
6
Q
Generators have
A
slip rings and carbon brushes
7
Q
Motors have
A
split rings/commutator and carbon brushes
8
Q
Diode
A
a component that only allows current to flow in one direction
