ELECTRODYNAMICS Flashcards
1
Q
magnetic flux linkage
A
as the product of the number of turns on the coil and the flux through the coil
2
Q
faradays law of electromagnetic induction
A
the emf induced is directly proportional to the rate of change of magnetic flux
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
diode
A
asa component that only allows current to flow in one direction
5
Q
the photoelectric effect
A
as the process that occurs when light shines on a metal and electrons are ejected
6
Q
threshold (cut-off) frequency
A
as the minimum frequency of incident radiation at which electrons will be emitted from particular metal
7
Q
work function
A
as the minimum amount of energy needed to emit an electron from the surface of metal
