inductors Flashcards
The current generated in a conductor by a changing magnetic field is
proportional to the rate of change of the magnetic field, this effect is called
inductance
Henry fulll name
American
Physicist Joseph Henry (1797-1878).
required to produce an emf of 1 volt in a conductor when the current in the
conductor changes at the rate of 1 Ampere per second.
1 henry
The amount of
inductance in an inductor is dependent on:
-no of coils
-material of core
-shape and size of core
-shape, size and arrangement of wire making up the coil
types of coil according to core
air core
iron core
ferrite iron core
passive electronic component that transfer electrical energy from
one electrical circuit to another circuit, or multiple circuits.
transformer
Magnetic flux is produced by
having alternating current flowing in the wire. The bigger the magnetic flux, the ______ the
induced voltage.
higher
time constant inductance
T = L/R
formula of inductance in series
add
formula of inductance in parallel
1/LT = 1/L1 +1/L2
