Question
When an electric current is passed through a conducting solution, there is a change of color of the solution. This indicates
- The heating effect of current
- The lightning effect of current
- The chemical effect of current
- The magnetic effect of current
Hint:
The change of color of the solution when an electric current is passed is due to the chemical effect of the electric current.
The correct answer is: The chemical effect of current
- The effects of current are produced when it is passed through a conducting solution.
- This can be determined by the outcome of the circuit.
- The change of color in a solution is a chemical effect of electric current.
