Definitions
|
Magnetic
Field : The region around a current carrying conductor
(or a magnet) where magnetic effects can be experienced is
called magnetic field. |
|
Mutual
Inductance : The property of two coils by virtue of which
each oppose any change of current flowing in the other is
called mutual inductance between two coils. |
|
Mass
Number : The total number of nucleons (protons plus neutrons)
called mass number (or atomic mass number) and is represented
by the symbol A. This name is used since the mass of a nucleus
is very closely A times the mass of one nucleon. A nucleus
with 7 protons and 8 neutrons thus has Z = 7 and A = 15.Clearly,
neutron number, N = A - Z. |
|
Mass
Defect : The difference between the actual mass of the
nucleus and the sum of masses of the constituent nucleons
is called mass defect i.e. Mass Defect, Δm = M - A. |
|
Modulation
Factor : The ratio of change of amplitude of carrier wave
to the amplitude of normal carrier wave is called the modulation
factor ma i.e. modulation
factor ma = Amplitude change of carrier wave / Normal carrier wave (unmodulated) |
|
Milky
Way : The galaxy to which sun belongs is called milky
way i.e. this is the galaxy in which we live. |
