1. Amongst which of the following is the correct about the flow of current in gasses and liquids?
- The flow of negative ion and positive ion is in the same direction
- The flow of positive ions is in one direction and the flow of negative ions is in the opposite direction
- Only positive ion flow in one direction
- None of the above
Answer: B) The flow of positive ions is in one direction and the flow of negative ions is in the opposite direction.
Explanation:
Due to ion mobility, electrical conduction occurs in gases and liquids. Positive ions flow one way and negative ions flow the other. In gases and liquids, the electric current is formed by this specific ion movement.
