current-electricity Question 34

Question: Q. 12. (i) Deduce the relation between current $I$ flowing through a conductor and drift velocity $v_{d}$ of the electrons.

(ii) Figure shows a plot of current ’ $I$ ’ flowing through the cross-section of a wire versus the time ’ $t$ ‘. Use the plot to find the charge flowing in $10 s$ through the wire.

Show Answer

Solution:

Ans. (i) According to the figure,

$Δ x = v_{d} Δ t$

Hence, amount of charge crossing area Antime $Δ t$

(ii) Charge flowing $= \sum I Δ t$

$\begin{aligned} = area under the curve & = [\frac{1}{2} \times 5 \times 5 + 5 (10 - 5)] C & = 37.5 C \end{aligned}$
