The maximum electric field in the filament will depend on factors such as the voltage applied and the material properties of the filament. It can be calculated using the formula E V/d, where E is the electric field, V is the voltage, and d is the distance across the filament.

When is the torque on an electric dipole in an electric field is maximum?
The torque on an electric dipole in an electric field is maximum when the dipole is aligned parallel or anti-parallel to the electric field lines. This occurs because the torque is given by the cross product of the electric dipole moment vector and the electric field vector, and it is maximum when the angle between them is 90 degrees.
What is the amplitude of the associated electric field?
The amplitude of the associated electric field refers to the maximum strength or intensity of the electric field. It represents the peak value of the electric field's magnitude.
Why flux is maximum when area is perpendicular to electric field?
When the area is perpendicular to the electric field, the maximum number of electric field lines pass through the area, resulting in the maximum flux. This occurs because the angle between the electric field lines and the normal to the area is at its smallest, maximizing the dot product that determines flux.
What is the process to calculate the maximum electric field strength in a given system?
To calculate the maximum electric field strength in a system, you need to determine the charge distribution and geometry of the system. Then, use the formula E k q / r2, where E is the electric field strength, k is the Coulomb's constant, q is the charge, and r is the distance from the charge. By finding the maximum value of E at any point in the system, you can determine the maximum electric field strength.
How does an electromagnetic light bulb work?
An electromagnetic light bulb works by passing an electric current through a filament, which heats up and produces light. The filament is enclosed in a glass bulb filled with a gas that helps to maintain the filament's temperature and prevent it from burning out. The electric current creates an electromagnetic field that excites the atoms in the filament, causing them to emit light.

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 is the amplitude of the electric field in a given region of space?
The amplitude of the electric field in a given region of space refers to the maximum strength or intensity of the electric field in that area. It represents the peak value of the electric field's magnitude at any point within that region.
Why does a magnet make the filament move in a light bulb?
When a magnet is brought near a light bulb, the magnetic field interacts with the electric current flowing through the filament, causing a force to be exerted on the filament. This force can make the filament move or vibrate, resulting in changes in the brightness or flickering of the light bulb.
How do you calculate the amplitude of a light wave?
The amplitude of a light wave is the maximum displacement of the electric or magnetic field from its equilibrium position. It can be calculated by measuring the maximum value of the field intensity at a specific point in space. This value is usually expressed in terms of volts per meter for electric field or teslas for magnetic field.
Which statement gives the relationship between the waves in the electric and magnetic fields in an electromagnetic wave?
In an electromagnetic wave, the electric and magnetic fields are perpendicular to each other and oscillate in phase. This means that when the electric field reaches its maximum strength in one direction, the magnetic field will also reach its maximum strength but in a direction perpendicular to the electric field.
What is a filament that glows white hot in electric light bulbs?
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
How electric bulbs works?
Electric bulbs work by passing an electric current through a filament, which heats up and produces light. The filament is typically made of tungsten, which has a high melting point. The light produced is a result of the filament glowing as it reaches high temperatures.
