Why is current constant in a non-uniform conductor?

Why is current 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.

Does current change with area of cross section?

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.

How does current depend on area of cross section?

The amount of current does depend on the cross section of a wire, that is, the for a given conductor, the resistance is doubled as the cross-sectional area is halved. The EMF provided by the voltage allows for current to flow.

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.

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.

(d) electric field. 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.
