NEET Physics Ohm's Law Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Electric field in a conductor | (i) Drift velocity of electrons |
| (b) Current density relation | (ii) Conductivity definition |
| (c) Ohm's law limitations | (iii) Proportionality of V and I |
| (d) Steady temperature of heating element | (iv) Heat loss to surroundings |
a-i, b-ii, c-iii, d-iv
a-ii, b-iv, c-i, d-iii
a-iv, b-ii, c-i, d-iii
a-iii, b-i, c-ii, d-iv
Correct Answer
Detailed Explanation
The electric field in a conductor leads to the drift velocity of electrons, while current density is related to conductivity. Ohm's law holds in many cases, but its limitations arise when V and I are not proportional. The steady temperature of a heating element is determined by the balance of heat loss to the surroundings.
