# NEET Physics Current Electricity Questions Solved

An electric current is passed through a circuit containing two wires of the same material, connected in parallel. If the lengths and radii of the wires are in the ratio of 4/3 and 2/3, then the ratio of the currents passing through the wire will be

(1) 3

(2) 1/3

(3) 8/9

(4) 2

(2) $\frac{{i}_{1}}{{i}_{2}}=\frac{{R}_{2}}{{R}_{1}}=\frac{{l}_{2}}{{l}_{1}}×{\left(\frac{{r}_{1}}{{r}_{2}}\right)}^{2}=\frac{3}{4}{\left(\frac{2}{3}\right)}^{2}=\frac{1}{3}$
