| LIST I | LIST II | ||
|---|---|---|---|
| A. | Resistance | I. | Property of the material |
| B. | Super conductor | II. | The capacity of supplying current in the circuit |
| C. | Specific resistance | III. | The collision of electrons while moving through the conductors. |
| D. | Ampere-hour | IV. | Motion of electrons through a conductor without any collision |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-III, B-IV, C-I, D-II
Each term from current electricity is matched with its meaning.
(A) Resistance — this matches (III) The collision of electrons while moving through the conductors. Resistance arises because the drifting electrons collide with the ions of the lattice and lose momentum.
(B) Super conductor — this matches (IV) Motion of electrons through a conductor without any collision. Below a critical temperature the resistance of a superconductor falls to zero.
(C) Specific resistance — this matches (I) Property of the material. The specific resistance (resistivity) depends on the material and the temperature, not on the length or area of the wire.
(D) Ampere-hour — this matches (II) The capacity of supplying current in the circuit. It is the unit of charge (1 A h = 3600 C) used to state how much charge a cell or battery can supply.
