A wire has non-uniform cross-section as shown in fig. steady current flows through it. The drift speed of electrons at point `P` and `Q` is `v_(P)` and `v_(Q)`

A wire has a non-uniform cross-section ai shown In figure. A steady current Is tlowint through it. Then the drift speed of tht electrons while going from A and B .........

A wire of non-uniform cross-section is carrying a steady current. Along the wire

A wire of non-uniform cross-section is carrying a steady current. Along the wire

A wire of radius R having uniform cross section in which steady current l is flowing. Then

A wire of radius R having uniform cross section in which steady current l is flowing. Then

(A): The current density remains constant in a conductor of non uniform cross-section, carrying steady current. (R): The drift speed of electrons is cosntant in a conductor of non-uniform cross-sec tion which is carrying current.

For the given conductor the drift speed of electrons at cross section I, II and III are v_(d_1) , v_(d_2) , " and v_(d_3) , then
