A pair of copper wires with the same length are joined in parallel. A potential difference is applied across the two ends of this parallel arrangement. Wire S has a diameter of $3.0\,\text{mm}$. Wire T has a diameter of $1.5\,\text{mm}$. What is the value of the ratio $\dfrac{\text{current in S}}{\text{current in T}}$?
- A$\frac{1}{4}$
- B$\frac{1}{2}$
- C2
- D4
