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 wire are in the ratio `(4)/(3)` and `(2)/(3)`, then the ratio of the currents passing through the wires will beA. `(1)/(3)`B. `(3)/(1)`C. `(4)/(3)`D. `(3)/(4)` |
