describe the electric current and its eeffect chapter
Answers
Answer:
The main effects are heating, chemical, and magnetic effects.
Heating Effect: When an electric current passes through a conductor (like a high resistance wire) the conductor becomes hot after some time and produces heat. This is called the heating effect of Electric Current.
Chemical Effect: The passage of an electric current through a conducting solution causes chemical reactions. As a result, bubbles of gas may be formed on the electrodes. Deposits of metal may be seen on electrodes. Changes in the color of solutions may occur. The reaction would depend on what solution and electrodes are used.
Magnetic Effect: When an electric current passes through a wire, it acts like a magnet. This is the magnetic effect of the electric current. If the electric current does not passes through, it loses its magnetic effect. These coils of wire are called electromagnets.
