It is pretty close to 0. I am sitting at a desk. However, I am also sitting on the planet earth which is revolving on its axis as well as rotating around the sun (approximately); the sun is rotating along with our arm of the Milky Way Galaxy, the Milky Way Galaxy is moving through space towards the Andromeda Galaxy and our local cluster is headed towards ... . My head starts spinning when I think of all the calculations required. Besides, what fixed frame of reference can I use to measure all these movements?
What else can I help you with?
Why velocity of current equal to velocity of light?
Because charge particles produces magnetic field which causes electromagnetic force that's why moving charges move with the velocity equal to the velocity of light.
In direct current charges carries have a drift velocity but in alternating current there is no net velocity of the charge carriers. Explain why?
In direct current the charge carries always flow in the same direction, while in alternating current they change direction repeatedly, meaning overall there is no net direction.
At what degree does a conductor have to pass through a magnetic field to get maximum induced current?
The induced current is maximum when the axis of the conductor, its velocity, and the magnetic field lines are all mutually perpendicular.
How does the current flowing in a conductor depend on the number of mobile charge carriers per unit length on their average velocity on the charge per carrier?
the flowing in the conductor is related as given by the relation... I=Vena v=drift velocity of electron e=charge on electron n=concentration of electron in the current carrying conductor . a=area
When an electric current flows through a long conductor how does each free electron moves?
The individual electrons will move back and forth, as they do when there is no current. You would have to do very careful statistics to notice that there are slightly more electrons moving in one direction than in the other: the drift velocity (average velocity due to current) of the electrons is typically a fraction of a millimeter per second.
What is the relationship between current, charge, and velocity in an electrical system where the current is equal to the charge multiplied by the velocity?
In an electrical system where current is equal to the charge multiplied by the velocity, the relationship is that the current flowing through the system is directly proportional to both the amount of charge and the velocity at which the charge is moving. This means that as either the charge or the velocity increases, the current flowing through the system will also increase.
A river current has a velocity of 5 kmh relative to the shore. A boat moves in the same direction as the current at 4 kmh relative to the river. How do you calculate the velocity of the boat relative?
The velocity of the boat relative to the shore is the vector sum of its velocity relative to the river and the velocity of the river current. In this case, it would be 4 km/h (boat's speed) + 5 km/h (current's speed), which equals 9 km/h.
Why velocity of current equal to velocity of light?
Because charge particles produces magnetic field which causes electromagnetic force that's why moving charges move with the velocity equal to the velocity of light.
Momentum is the product of mass and what of an object?
mass multiplied by velocity gives momentum.
What relation between electric current and drift velocity?
The drift velocity of free electrons in a conductor is directly proportional to the magnitude of the electric current flowing through the conductor. This means that as the current increases, the drift velocity of the electrons also increases. The relationship is described by the equation I = nAvq, where I is the current, n is the number density of charge carriers, A is the cross-sectional area of the conductor, v is the drift velocity, and q is the charge of the charge carrier.
In direct current charges carries have a drift velocity but in alternating current there is no net velocity of the charge carriers. Explain why?
In direct current the charge carries always flow in the same direction, while in alternating current they change direction repeatedly, meaning overall there is no net direction.
What is a downward flowing air current?
A current of air with its velocity directed downwards or in a direction below the horizontal. Mathematically v.n < 0 where v is the velocity vector and n is the upward normal at the surface.
Is constant speed current velocity?
No, it is not. Basically speed is a scalar whereas velocity is a vector.A car going round a circular track at constant speed has a velocity which is changing at every moment.
Difference between velocity and current modulation in klystron?
Velocity modulation in a klystron involves the interaction between the electron beam's velocity and the RF field to produce amplification. Current modulation, on the other hand, involves varying the electron beam's current to control the amplification of the RF signal. In summary, velocity modulation affects the electron beam's speed, while current modulation affects the electron beam's density in a klystron.
How can velocity be changed?
Velocity can be changed by applying a force in the direction of motion. An increase in force will result in an increase in velocity, while a decrease in force will cause velocity to decrease. Another way to change velocity is by changing the direction of motion, which can be achieved by applying a force perpendicular to the current motion.
What is a current meter?
it is an instrument to determine the velocity of flow at required point in a flowing stream.
What term describes the speed of the flow of water in a river or a river stream?
velocity
