Question: A current Iis 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 $v_P$ and $v_Q$ respectively, then


1) $v_P = v_Q$
2) $v_P = \frac{1}{2}v_Q$
3) $v_P = \frac{1}{4}v_Q$
4) $v_P = 2 v_Q$
Solution: Explanation: No Explanation
Electric Conduction Ohm's Law Resistance
