Electricity, simply put, is
the flow of electric current along a conductor
. This electric current takes the form of free electrons that transfer from one atom to the next. Thus, the more free electrons a material has, the better it conducts.
What is the principle of electric motor answer?
The electric motor works on the
principle of magnetic effects of current
. Its principle is when a rectangular coil is placed in a magnetic field and current is passed through it, the coil rotates as a result of the forces acting on the coil.
What is the principle of an electric motor class 10th?
The principle of an electric motor is
based on the current carrying conductor which produces magnetic field around it
. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
What is the basic law of electricity?
I = V / R or V = IR
or R = V/I. Where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms.
What is electric motor explain with diagram?
1)
When electric is passed into the rectangular coil, magnetic field is produced around the coil
. 2)The magnetic field of horse shoe type interacts with the magnetic field on the coil and causes the coil to rotate continuously.
What are the main parts of electric motor?
- A power supply – mostly DC for a simple motor.
- Field Magnet – could be a permanent magnet or an electromagnet.
- An Armature or rotor.
- Commutator.
- Brushes.
- Axle.
What is the role of commutator in electric motor?
The commutator
assures that the current from the generator always flows in one direction
. … On DC and most AC motors the purpose of the commutator is to insure that the current flowing through the rotor windings is always in the same direction, and the proper coil on the rotor is energized in respect to the field coils.
How many types of electric motors are there?
Distinctions between different types of electric motors relates to their unique operation, voltage, and application requirements. There are
at least a dozen different types of electric motors
, but there are two main classifications: alternating current (AC) or direct current (DC).
What does Joule’s law state?
noun Physics. the principle that
the rate of production of heat by a constant direct current is directly proportional to the resistance of the circuit and to the square of the current
. the principle that the internal energy of a given mass of an ideal gas is solely a function of its temperature.
How many types of electrical laws are there?
| No. Description | 1 Ohm’s Law | 2 Kirchhoff’s Laws | 3 Thévenin’s Theorem | 4 Norton’s Theorem |
|---|
Why does electricity travel through a person?
Electricity is everywhere, even in the human body. Our cells are specialized to conduct electrical currents. … This is due to
a slight imbalance between positive and negative ions inside and outside the cell
. Cells can achieve this charge separation by allowing charged ions to flow in and out through the membrane.
What is electric motor and explain its working?
An electric motor is an
electrical machine that converts electrical energy into mechanical energy
. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.
What is electric motor Short answer?
The electrical motor is
a device that converts electrical energy into mechanical energy
. In simple terms, the electrical motor is a device used for producing rotational energy.
What is motor diagram?
AC Motor Diagrams – Basic Stator and Rotor Operation. An AC Motor converts electric energy into mechanical energy. An AC Motor uses alternating current – in other words, the direction of current flow changes periodically.
What is the price of electric motor?
| Power Min Price Max Price | 10-100 KW Rs 3500/Piece Rs 8000/Piece | <10 KW Rs 2000/Piece Rs 8500/Piece |
