Two copper wires of equal length but different cross-sectional areas carry the same current. Which of the following statements is true regarding the drift velocities of electrons in the two wires?

A current $I$ is passing through a wire having two sections $P$ and $Q$ of uniform diameters $d$ and $d/2$ respectively. If the mean drift velocity of electrons in sections $P$ and $Q$ is denoted by ${v_{\rm{P}}}$ and ${v_{\rm{Q}}}$ respectively, then

There is a current of \begin{array}{*{20}{l}} {{\rm{0}}{\rm{.21}}\,\,{\rm{A}}} \end{array} in a copper wire whose area of cross-section is ${10^{ - 6}}\,{{\rm{m}}^2}$. If the number of free electrons per ${{\rm{m}}^3}$ is $8.4\,\, imes \,{10^{28}}$, then find the drift velocity,$\left( {e = 1.6\,\, imes \,\,{{10}^{ - 19}}\,\,{\rm{C}}} \right)$

A current of $5A$ passes through a copper conductor (resistivity $= 1.7 imes {10^{ - 8}}\Omega m$) of radius of cross section 5mm. Find the mobility of the charges if their drift velocity is $1.1 imes {10^{ - 3}}\,m/s$

Current flows through a metabolic conductor whose area of cross-section increases in the direction of the current. If we move in this direction,

If the current in a conductor is doubled, keeping the area of cross-section and the number density of charge carriers constant, the drift velocity:

Drift velocity ${v_d}$ varies with the intensity of electric field as per the relation

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

A potential difference $V$ is applied to a copper wire of length $l$ and thickness $d$. If $V$ is doubled, the drift velocity

The direction of drift velocity of electrons in a metallic conductor is:

The electron dirft speed is small and the charge of the electron is also small but still, we obtain large current in a conductor. This is due to
