a. `i_1 and i_2`
b. `j_1 and j_2`
c. `(v_d)_1 and (v_d)_2`
(drift velocity) where I is current, j is current density, and V is drift velocity.

The current density in a metallic conductor varies drift velocity (V_d) as

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 : 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.

a. A steady current flows in a metallic conductor of non - uniform cross section. State which of the quantities i.e., current density, electric field, and drift velocity, current density, electric field, and drift velcoity remain constant? b. A steady current passes through a cylindrical conductor. Is there an electorn field inside the conductor?

Current 'I' flowing through a metallic wire of area of cross-section 'a' is given by the equation I = "naev"_(d) . What is the meaning of the symbols 'n' and ' v_(d) '?

A current of "1.6A" is flowing through "h" wire having cross- sectional area 1mm^(2) .If density of free electrons in the material of the wire is 10^(29) per m^(3) ,the drift velocity of electrons will be:-

When current I is made to flow in a wire of radius r, the drift velocity is v_d . If the same current is passed through a wire of radius 2r, then drift velocity will be:
