Two identical coaxial coils P and Q carrying equal current in the same direction are brought nearer. The current in:
Two identical coaxial coils P and Q carrying equal current in the same direction are brought nearer. The current in:
Updated On: Nov 6, 2024
- P increases while in Q decreases
- Q increases while in P decreases
- Both P and Q increase
- Both P and Q decrease
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
When two current-carrying coils are brought closer, their mutual inductance increases, and the self-inductance opposes the increase in magnetic flux, resulting in a decrease in current in both coils.

Aldehydes are generally more reactive than ketones in nucleophilic addition reactions due to steric and electronic reasons. Sterically, the presence of two large groups in ketones hinders the attack of nucleophile to carbonyl carbon than in aldehydes. Electronically, aldehydes are more reactive than ketones because two alkyl groups reduce the electrophilicity of the carbonyl carbon more effectively than in the former- CUET (UG) - 2024

The transition metals are very hard and have low volatility. Their melting and boiling points are high. In any row, the melting points of these metals rise to a maximum at d5 and fall regularly as atomic number increases. The high melting points of these metals are attributed to the involvement of greater number of electrons from (n– 1)d in addition to ns electrons in the interatomic metallic bonding.- CUET (UG) - 2024
