When a wire carries a current of `1.20 A`, the drift velocity is `1.20xx10^-4 m//s`. What is the velocity when the current is `6.00 A`?

A long straight wire carries a current of 10 A. An electron travels perpendicular to the plane of this wire at a distance 0.1 m with a velocity of 5.0 xx10^(6)m//s. What is the force acting on the electron due to the current in wire ?

When current is 4 A in a conductor the drift velocity is v_(d) . When the current is 3 A the drift velocity will be

When current is 4 A in a conductor the drift velocity is v_(d) When the current is 3 A the drift velocity will be

A long straight wire carries a current of 10 ampere. An electron travels with a velocity of 5.0x10 ms parallel to the wire at 0.1 m from it and in a direction opposite to the current. What force is exerted on the electron ?.

If the radius of a wire carrying current is doubled, the drift velocity of the electrons will be :

A copper wire of 2.5 xx 10^-6 m^2 area carries a current of 1.6A. If the number density of the electrons in the wire is 8 xx 10^28//m^3 , then calculate the drift speed of the electrons in the wire (e = 1.6 xx 10^-19 C)

A conductor wire having 10^29 free electrons / m^3 carries a current of 20A. If the cross-section of the wire is 1mm^2 , then the drift velocity of electrons will be :
