Motor AC Generator (Alternator) Transformer
An electrical Generator is a machine which converts mechanical energy (or power)
into electrical energy (or power).
Principle :
It is based on the principle of production of dynamically (or motionally) induced e.m.f(Electromotive Force). Whenever a conductor cuts magnetic flux, dynamically induced e.m.f.
is produced in it according to Faraday's Laws of Electromagnetic Induction. This e.m.f.causes a current to flow if the conductor circuit is closed.
Hence, the basic essential parts of an electric generator are :
A magnetic field and
A conductor or conductors which can so move as to cut the flux.
Construction :
A single-turn rectangular copper coil abcd moving about its own axis in a magnetic field
provided by either permanent magnets or electromagnets. The two ends of the coil arejoined to two split-rings which are insulated from each other and from the central shaft. Two
collecting brushes (of carbon or copper) press against the slip rings.

DC Generator AC Generator (Alternator) Transformer
An electric motor is a machine which converts electrical energy into mechanicalenergy.
Principle:
It is based on the principle that when a current-carrying conductor is placed in a magneticfield, it experiences a mechanical force whose direction is given by Fleming's Left-hand ruleand whose magnitude is given by
Force, F = B I l newton
Where B is the magnetic field in weber/m2.
I is the current in amperes and
l is the length of the coil in meter.
The force, current and the magnetic field are all in different directions.
If an Electric current flows through two copper wires that are between the poles of a
magnet, an upward force will move one wire up and a downward force will move the otherwire down.

Figure 3 : Torque in DC Motor Figure 4 : Current Flow in DC Motor
The loop can be made to spin by fixing a half circle of copper which is known as
commutator, to each end of the loop. Current is passed into and out of the loop by brushesthat press onto the strips. The brushes do not go round so the wire do not get twisted. This
arrangement also makes sure that the current always passes down on the right and back on
the left so that the rotation continues. This is how a simple Electric motor is made.

Principle :
A.C. generators or alternators (as they are usually called) operate on the same fundamental
principles ofelectromagnetic induction as D.C. generators.
Alternating voltage may be generated by rotating a coil in the magnetic field or by rotatinga magnetic field within a stationary coil. The value of the voltage generated depends on-
the number of turns in the coil.
strength of the field.
the speed at which the coil or magnetic field rotates.

Working :Consider a rectangular coil having N turns and rotating in a uniform magnetic field with an
angular velocity of radian/second. Maximum flux m is linked with the coil when its plane
coincides with the X-axis. In time t seconds, this coil rotates through an angle = . position , the component of the flux which is perpendicular to the plane of the
coil is = m cos t. Hence flux linkage at any time are N=Nm cos t.
According to Faraday's Laws of Electromagnetic Induction, the e.m.f. induced in the coil is
given by the rate of change of flux linkage of the coil. Hence the value of the induced e.m.f.
is
e = - d(N)/dt volt= - N d(m cos t) / dt volt= - Nm ( t) volt= Nm t volt= Nm volt ----------------------- (i)When the coil turned through 90 i.e. when = 90, then sin ,

DC Generator AC Generator (Alternator) Motor
A transformer is a static piece of apparatus by means of which electric power in one circuit
is transformed into electric power of the same frequency in another circuit. It can raise orlower the voltage in a circuit but with a corresponding decrease or increase in current.Principle :
In brief, a transformer is a device that
transfers electric power from one circiut to another.
it does so without a change of frequency.
it accomplishes this by electromagnetic induction and
where the two circuit are in mutual inductive influence of each
other.Working of Transformer E.M.F. Equation of a Transformer Voltage Transformation
In it's simplest form it consist of, two inductive coils which are electrically separated but
magnetically linked through a path of low reluctance. If one coil (primary) is connected to
source of alternating voltage, an alternating flux is set up in the laminated core, most of which is
linked with the other coil in which it produces mutually-induced e.m.f. (according to Faraday'sLaws of Electromagnetic Induction. If the second coil (secondary) circuit is closed, a current flows
in it and so electric energy is transferred (entirely magnetically) from the first coil to the second
coil.
Let N1 = No. of turns in primary

N2 = No. of turns in secondary
m = Maximum flux in core in webers = Bm x Af = Frequency of a.c. input in Hz.
The flux increases from it's zero value to maximum value m in one quarter of the cycle i.e.in 1/4 f second.
Therefore, r.m.s value of e.m.f./turn = 4.44 m voltsNow, r.m.s value of induced e.m.f in the whole primary winding
= ( induced e.m.f. / turn ) x No. of primary winding
E1 = 4.44 f N1m ------------------- ( i )Similarly, r.m.s. value of e.m.f. induced in secondary is,
E2 = 4.44 f N2m------------------- ( ii )
From the above equations (i) and (ii), we get
