Collisions between conduction electrons and atoms
The release of conduction electrons from parent atoms
Mutual collisions between metal atoms
Mutual collisions between conducting electrons
Answer is Right!
Answer is Wrong!
The correct answer is: A. Collisions between conduction electrons and atoms.
When an electric current passes through a metallic conductor, the electrons in the conductor are forced to move. This movement causes the electrons to collide with the atoms in the conductor. These collisions cause the atoms to vibrate, which produces heat.
The other options are incorrect because:
- Option B is incorrect because the conduction electrons are already free to move. They do not need to be released from parent atoms.
- Option C is incorrect because the metal atoms are not moving. The only thing that is moving is the conduction electrons.
- Option D is incorrect because the conduction electrons do not collide with each other. They only collide with the atoms in the conductor.
