When a current flows through a conductor of non-uniform cross section the quantity that remains constant is?

Only current remains constant. In a metallic conductor of non-uniform cross-section, only the current remains constant along the whole length of the conductor.

When a steady current flows through a metal conductor of non-uniform cross section then drift velocity is?

Therefore, drift velocity is directly proportional to the cross sectional area i.e. vd∝1A. Hence, if the area of the cross section is non-uniform, the drift velocity of the electrons is not constant for the whole length of the conductor.

Which one is non-uniform cross section?

The cross section of the metallic conductor is non-uniform.

How is current flow related to the area of cross section?

Current flow directly proportional to cross section area of conductor,inversely proportional to length of a conductor,depends on the type of material.

When a current I is flowing through a conductor?

Ohm’s law relates the current flowing through a conductor to the voltage V and resistance R; that is, V = IR. An alternative statement of Ohm’s law is I = V/R. When an electric current flows in an external magnetic field, it experiences a magnetic force, as in electric motors.

What is the current flowing through the conductor?

When electrical current is applied to a conductor, all the electrons inside it gets charged and possess uniform direction. This results in the distribution of electrical charges from one electron to other. And hence, electric current flows.

When current flows through a conductor then?

When current flows through a conductor such as a copper wire, all of those electrons that were previously moving about randomly get together and start moving in the same direction. A very interesting effect then happens: The electrons transfer their electromagnetic force through the wire almost instantaneously.

Does electric current depends on area of cross section?

The electric current will remain constant in a wire whose cross-sectional area is increased linearly from its one end to the other, is connected across a battery of V volts. Because current is the only quantity that does not depend on the area of cross- sections of the wire.

When no current flows through a conductor?

Another way to look at this is, since there is no current in the conductor it implies that the net displacement of all the electrons has to be 0. This means they will have 0 drift velocity. So, at any instant the average velocities of all the free electrons at any instant will be 0. This option is correct.

When current flows through a conductor its temperature?

Due to this transfer of energy through collision, the heat is generated in the conductor. So, the temperature of the conductor increases because of the current flow through it. So, we can say that when electric current flows through a conductor, the temperature of the conductor rises.

What causes the current to flow in a conductor?

When an electric current flows in a conductor, it flows as a drift of free electrons in the metal. Electricity flows easily through a conductor because the electrons are free to move around in the object. Whenever there is a movement of electrons through a conductor, an electric current is created.

Why current is constant in a non uniform conductor?

When a steady current flows in a metallic conductor of non-uniform cross-section, the current flowing through the conductor is constant. Current does not depend on the area of the conductor, hence it remains a constant. Current density, electric field, and drift speed are inversely proportional to the area of cross-section.

Does current depend on the area of the conductor?

Current does not depend on the area of the conductor, hence it remains a constant. Current density, electric field, and drift speed are inversely proportional to the area of cross-section. When study or constant current flow in a metallic conductor of non-uniform cross-section then draft speed is

What is the quantity/quantities constant along the length of the conductor?

The quantity/quantities constant along the length of the conductor is/are (1) current, electric field and drift speed (2) drift speed only (3) current and drift speed (4) current only When a steady current flows in a metallic conductor of non-uniform cross-section, the current flowing through the conductor is constant.

What is a steady current in a metallic conductor?

A steady current flows in a metallic conductor of non-uniform cross section. Which of the following quantities are constant along the conductor: current, current density, electric field, or drift speed? Conductor of non-uniform cross section has area varying at different places for same current, which is steady current.
