What happens if the relative speed between the rotating flux of stator and rotor of the induction motor is zero?
if the relative speed of magnetic flux of stator and rotor becomes zero there will be no back emf and eventually the rotor gets zero speed
Technical team names for electronics engineers?
zero flux given
When pole flux of dc motor is zero what is its speed?
when the pole flux is zero there is no induced emf in the armature conductor of dc machine as a result of this there is no back emf for controlling action so speed become dangerously high or we can say it will be infinite.
What are the functions of the flux ingredients?
to remove oxides to the surface being soldered
What is the relation between voltage and magnetic flux?
A magnet field is the area surrounding a magnet within which the effects of that field may be observed.A magnetic field is represented by imaginary lines of force that we call magnetic flux. Magnetic flux (symbol, the Greek letter phi) is measured in webers (pronounced 'vay-bers'); the intensity of the magnetic flux is called magnetic flux density which is defined as the flux per unit area, measured in webers per square metre, which is given the special name, the tesla.
What is maximum and minimum electric flux?
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
What will be value of flux if the surface does not enclose any charge?
If the surface does not enclose any charge, the electric flux through the surface will be zero. This is because electric flux is a measure of the total electric field passing through a surface, and if there are no charges within the surface, there will be no electric field passing through it.
When magnetic flux through surface is zero?
When the magnetic flux through a closed surface is zero, it means that the magnetic field lines entering the surface equal the field lines leaving it. This can occur when the surface encloses no magnetic sources or when it lies parallel to the magnetic field lines. Mathematically, it can be expressed as ∮B⋅dA = 0, where B is the magnetic field and dA is the differential area vector.
A Gaussian surface does not enclose a charge Does it mean that E equals 0 on its surface?
No.there can be electric field on the Gaussian surface even if the charge enclosed by it is zero.However ,net flux will be zero through the surface.
When electric flux is zero then electric field is also zero why?
The electric flux depends on charge, when the charge is zero the flux is zero. The electric field depends also on the charge. Thus when the electric flux is zero , the electric field is also zero for the same reason, zero charge. Phi= integral E.dA= integral zcDdA = zcQ Phi is zcQ and depends on charge Q, as does E.
What are the two main types of flux?
Types of flux - Electric and Magnetic Flux. Electric field flux through a closed surface is equal to the change enclosed in the surface, or the rate of change of magnetic flux is equal to the induced voltage around the surface.
Can there be any magnetic flux through closed surface?
No, according to Gauss's law for magnetism, the total magnetic flux through a closed surface is zero. This is because magnetic monopoles do not exist, so the magnetic field lines always form closed loops.
What is the direction of heat flux on isothermal surface?
Direction of heat flux on an isothermal surface is always normal to the surface.
What does magnetic flux mean in physics?
Magnetic flux is a measure of the magnetic field through a given area. It quantifies the number of magnetic field lines passing through a surface. It is an important concept in electromagnetic theory and plays a crucial role in understanding magnetic phenomena.
Is flux is directly proportional to charge?
Yes, according to Gauss's law, the flux through a closed surface is directly proportional to the charge enclosed by that surface. This is known as the electric flux theorem.
How can one determine the electric flux through a surface?
To determine the electric flux through a surface, you can use Gauss's Law. This law states that the electric flux through a closed surface is equal to the charge enclosed by the surface divided by the permittivity of free space. The formula for electric flux is E A cos(), where E is the electric field, A is the area of the surface, and is the angle between the electric field and the normal to the surface.
How can we calculate the flux for hemispheres of different radii?
To calculate the flux for hemispheres of different radii, you can use the formula for flux, which is the surface integral of the vector field over the surface of the hemisphere. The flux can be calculated by taking the dot product of the vector field and the normal vector to the surface, and then integrating over the surface area of the hemisphere. The formula for flux is given by F dS, where F is the vector field, dS is the differential surface area element, and the integral is taken over the surface of the hemisphere.
