Verified by Experts

Apply Bernoulli.s theorem : `(1)/(2)rhov_(1)^(2)+rhogh=(1)/(2)rhov_(2)^(2)+0` , find `v_(2)`
Now apply principle of continuity :
`A_(1)v_(1)=A_(2)v_(2)`
`(pir_(1)^(2))v_(1)=(pir_(2)^(2))v_(2)` find `r_(2)`

A constant voltage is applied across a wire of constant length then how drift velocity of electrons depends on area of cross-section of wire.

Statement I: A wire of uniform cross-section and uniform resistivity is connected across an ideal cell. Now the length of the wire is doubled keeping volume of the wire constant. The drift velocity of electrons after stretching the wire becomes one-fouth of what it was before stretching the wire. Statement II: If a wire (of uniform resistivity and uniform cross section) of length l_0 is stretched to length nl_0 , then its resistance becomes n^2 times of what it was before stretching the wire (the volume of wire is kept constant in stretching process). Further at constant potential difference, current is inversely proportional to resistance. Finally, drift velocity of free electron is directly proportional to current and inversely proportional to cross-sectional area of current carrying wire.
