What is the principle of generator using motor?
Generator principle: a current moving relative to a magnetic field will have a voltage induced into it.Motor principle: a current-carrying conductor within a magnetic field will experience a force that will try to push that conductor out of the field.
What is the working principle of a cross coil megger?
A cross coil megger operates on the principle of electromagnetic induction to measure insulation resistance. It consists of two coils positioned perpendicular to each other, where one coil generates a magnetic field when an electric current flows through it. The insulation resistance being tested induces a current in the second coil, and the resulting deflection on a calibrated scale indicates the level of insulation resistance. This device is essential for assessing the integrity of electrical insulation in various applications.
Which principle is used in a DC motor?
Current carrying conductor kept in a magnetic field gets deflected. This is the basic principle. In short Lorentz force causes the rotation
What is the principle of operation of a repulsion motor?
A repulsion motor operates on the principle of electromagnetic repulsion between the stator and rotor. When the stator is energized with alternating current, it creates a rotating magnetic field that induces current in the rotor. This induced current, in turn, generates its own magnetic field, which interacts with the stator's field, resulting in a repulsive force that causes the rotor to rotate. The motor typically requires a commutator to ensure that the rotor's magnetic field is properly aligned for continuous rotation.
What principle of venturi meter?
the basic principle on which a Venturimeter works is that by reducing the cross-sectional area of the flow passage, a pressure difference is created and by measuring this pressure difference, discharge through the pipe can be determined. formula to find actual discharge is=amount of fluid collected/time taken it works on the principle of bernoulli"s equation
Why do electric field has never cross each other?
Electric field lines do not cross each other because the electric field at any point is determined by the net effect of all the charges in the vicinity. If field lines were to cross, it would imply that two different field strengths or directions would be acting on the same point, which is not physically possible. This principle is based on the superposition principle in physics.
Where do magnetic field lines cross?
Magnetic field lines don't cross.
What are steno's principles?
They are: 1) Principle of Superposition 2) Principle of Original Horizontality 3) Principle of Lateral Continuity 4) Principle of Cross-Cutting relationships
What do you understand by field equivalence principle?
The eqivalence principle is a principle that replaces the actual source i.e (antenna , transmitter) by eqivalent sources
Which is a cross filed microwave tube?
Magnetron are know are cross field microwave tube because the E field and M field are perpendicular to each other
Do electric field lines cross?
No, electric field lines do not cross each other. If they did, it would imply that there are multiple directions for the electric field at the same point, which is not possible. The electric field lines always repel or attract each other, but they never cross.
What is the principle of generator using motor?
Generator principle: a current moving relative to a magnetic field will have a voltage induced into it.Motor principle: a current-carrying conductor within a magnetic field will experience a force that will try to push that conductor out of the field.
Is it possible for electric field lines to cross each other?
No, electric field lines cannot cross each other because they represent the direction of the electric field at any given point, and if they were to cross, it would imply that the electric field has multiple directions at that point, which is not physically possible.
Who was responsible for defining the principle of cross transfer of evidence?
Edmond Locard, a French forensic scientist, is credited with defining the principle of cross-transfer of evidence, stating that when two objects come into contact, there is an exchange of materials between them. This principle forms the basis of trace evidence analysis in forensic science.
Do magnetic field lines cross?
No.No.No.No.
does magnetic field lines cross?
Never
What electrical principle is used in a magnetic breaker?
megnetic field and current
