Distinction between the right-hand and left-hand rule
Fleming’s left-hand rule is used for electric motors, while
Fleming’s right-hand rule
is used for electric generators.
Which rule is used in AC motor?
In a simplified way,
Fleming’s left-hand rule
can describe motion in any of the multitude of different types of electric motors. DC, AC, Brushed, Brushless, Induction – all of these use the same concepts (1 electromagnetic field, 1 field that is either magnetic or electromagnetic, 1 force generated) to generate motion.
Which rule is used in AC generator?
(for generators) shows the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It can be used to determine the direction of current in a generator’s windings.
Which rule is used for generator?
Working principle of a generator alternator
Electric generators and generator alternators follow
the Fleming’s Right Hand Rule
. The Fleming’s Right Hand Rule determines the direction of the movement of the conductor, the magnetic field and the induced current.
What is working principle of AC generator?
AC generators work on the principle of
Faraday’s law of electromagnetic induction
. This law states that electro motive force is generated in a current carrying loop that is placed in a uniform magnetic field. … When the coil in the generator starts moving, the arm AB starts moving upwards and the arm CD moves downwards.
Does a generator make AC or DC?
Generators are capable of both AC and DC power
. Alternators usually are made for A/C (alternating current) applications, hence the name “alternator”.
What is the difference between AC generator and DC generator?
AC generator is a mechanical device that converts mechanical energy into AC electrical power. DC generator is a mechanical device that converts mechanical energy into DC electrical power. In an AC generator, the
electrical current reverses direction periodically
.
What is the cost of AC motor?
| General Purpose Motors Min Price Max Price | ABB General Purpose Motors ₹6666 ₹44253 | Oswal General Purpose Motors ₹4660 ₹37965 |

What is the difference between an AC and DC motor?
The most obvious difference is the
type of current each motor turns into energy
, alternating current in the case of AC motors, and direct current in the case of DC motors. AC motors are known for their increased power output and efficiency, while DC motors are prized for their speed control and output range.
How does the left hand rule work?
The direction of the force can be found using Fleming’s left-hand rule.
Hold your thumb, forefinger and second finger at right angles to each other
: the forefinger is lined up with magnetic field lines pointing from north to south. the second finger is lined up with the current pointing from positive to negative.
What is the left hand generator rule?
: a rule in electricity: if
the thumb and first two fingers of the left hand are arranged at right angles to each other on a conductor and the hand oriented
so that the first finger points in the direction of the magnetic field and the middle finger in the direction of the electric current then the thumb will point in …
What is the left hand rule for generator action?
The left-hand rule is summed up as follows:
The first finger of the left hand is pointed in the direction of the magnetic lines of force
(north to south), the thumb is pointed in the direction of movement of the conductor through the magnetic field, and the second finger points in the direction of the induced emf.
What is Fleming left hand rule and right hand rule?
| Left-Hand Rule Right-Hand Rule | The purpose of the rule is to find the direction of motion in an electric motor The purpose of the rule is to find the direction of induced current when a conductor moves in a magnetic field. |

What are the two main parts of an AC generator?
There are two main components in the generator,
the rotor and the stator
. The generator must also have a source of DC current to magnetize the rotor, called the exciter.
What are the advantages of AC generator?
Advantages of ac generators :
AC is very easy and efficient to transmit over a long distance rather than DC
. The design of the AC generator is fairly simpler than DC generator type. No need for matching a voltage. Cost of ownership is lower.
What is AC generator with diagram?
Principle: It works on the principle of Faraday’s law of electromagnetic induction. Whenever a coil is rotated in a uniform magnetic field about an axis perpendicular to the field, the magnetic flux linked with coil changes and an induced emf is set up across its ends.
