When a current flows through a conductor of non-uniform cross section?

When a current flows through a conductor of non-uniform cross section?

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

When a steady current flows through a conductor of non-uniform cross section a physical quantity which does not remain constant is?

A : When a steady current flows through a conductor of non – uniform cross-section , the current density , electric field and drift velcoity do not remain constant. R : For a constant current the current density electric field and drift velocity are inversely proportional to cross – sectional area.

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

When a steady current flows through a metal conductor of non-uniform cross-section , then drift velocity is. Inversely proportional to the square of area of cross-section.

Does cross-sectional area affect current?

The cross section area does affect the resistance of the cable and so will affect the overall current flowing. The current flowing in one end will still equal the current flowing out the other end.

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 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.

What is meant by cross section of conductor?

A cross section is the two-dimensional area you would get by cutting through the a conductor with a plane. For eg., a cylindrical conductor, if cut the normal way, has a circular cross section.

What is a cross section in math?

In geometry and science, a cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces. Cutting an object into slices creates many parallel cross-sections.

When current passes through a wire of non uniform cross section which of the following quantities are independent of the cross section?

The charge crossing in a given time interval is independent of the area of cross-section of the wire.

What happens when current is passed through a conductor?

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. The result is that even though the individual electrons move slowly, the current itself moves at nearly the speed of light.

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.

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.

How does a non-uniform conductor work?

Seniors share their 9 special benefits hacks! Conductor of non-uniform cross section has area varying at different places for same current, which is steady current. By the very definition of current, charges coming in at one end have to move out at the other end at any moment. So whatever the cross section, current remains same all along.

What passes through a wire of non-uniform cross section?

[SOLVED] A current passes through a wire of non – uniform crosssection. Which of the following quantities are independent of the cross – section? A current passes through a wire of non-uniform crosssection. Which of the following quantities are independent of the 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
