A steady current I is passed through a conductor at room temperature for time t. It is observed that its temperature rises by \(0 \cdot 5^{\circ} {C}\) . If 2 I current is passed through the conductor (at room temperature) for the same duration, the rise in its temperature will be approximately:
- \(1 \cdot 0^{\circ} {C}\)
- \(1.5^{\circ} {C}\)
- \(2 \cdot 0^{\circ} {C}\)
- \(4 \cdot 0^{\circ} {C}\)
Answer
(D) 4 0^ C
