Question

When electric current is passed through a conducting solution, there is a change of colour of the solution. This indicates

• A. the chemical effect of current.
• B. the heating effect of current.
• C. the magnetic effect of current.
• D. the lightning effect of current.

Answer 1

The correct option is A the chemical effect of current.

As their is a change in the colour of the solution, their must be some chemical reaction going inside the solution when current is passing through it.
Hence it is showing chemical effect of current.
