1.
| Assertion (A): | Nichrome wire gets hot when current passes through it. |
| Reason (R): | Nichrome is a high-resistance alloy, so electrical energy is converted to heat energy more effectively than in copper. |
2.
| Assertion (A): | A conductor gets heated when electric current flows through it. |
| Reason (R): | Heating occurs only in metallic conductors that have no resistance. |
