Question

two conductor wire X and Y of same diameter but different material are joined in series across a battery if the number density of electron in X is thrice than that in Y then find ratio of drift velocity of electron in two wires​

Answer 1

Answer:

3:1

Explanation:

where x is equal to 3 and y is equal to 21

Answer 2

Answer:

mark it as BRAINLIEST....

BCOZ IT IS THE CORRECT ONE...!!!

V = I / Anq

v= drift velocity

A= cross sectional area

n=charge density

I= current

I is inversely proportional to the charge density/ number density of electrons

assume charge density be X1 in conductor y. then conductor X will have 2(X1) charge density.

Therefore, v in X/ v in y = 1/2
