agar aapko mechanics aata hai to EMI is nt difficult!!!!!!!!!!!!!!!!
analogue table of mechanics and EMI and AC
the role played by....in mechanics is played by..........in emi
.........mechanics..............................................................EMI and AC
1) x = disaplacement -------------------------------------------------------q = charge
2) v = dx / dt......................................................................I = dq / dt
3)a = dv/dt.........................................................................dI/ dt
4)m = mass..................................................................... L = self inductance
5) p = mv..........................................................................phi = LI
6)F = dP/dt=ma...............................................................E = d(phi)/dt=LdI/dt
7)power = F.V ................................................................P = E . I
8)K.E= 1mv2 ...................................................................E = 1/2L I2
....................................................................................................................
WHERE phi is rate of change of flux....I = current
some imp. points in EMI and AC
1) self inductance of a coil depends upon....
a)total no. of turns/ unit length
b)dimensions of the coil
c)permeability of material
2)Mutual inductance depends upon
a)total no. of turns/ unit length
b)dimensions of the coil
c)permeability of material
d)orientation of the 2 coils
PS: both of the above donot depend upon material of the wire and amt. of current passed through the coil
3)A capacitor acts as a block fr DC but provide an easy path fr AC while an inductor provides an easy path fr DC while an opposing path for AC
4)An AC circuit can be regulated by using capacitor , inductor and resistor too
but fr DC only resistors are used
5)If a wire carrying current is brought near a circular loop and if..........
a)current is inc. in the wire , the induced current in the loop will follow opposite direction and if current is dec. then the induced current in the loop will follow same direction...................
