Question

IV. Answer the following
12. Differentiate between heating effect and magnetic effect of electric current. Name two
devices workingon electric and magnetic effect of electric current.
(2)
the factors Sansible for rusting? Name​

Answer 1

Explanation:

When an electric current is passed through a high resistance wire, the Resistance wire becomes very hot and produces heat. This is called heating effect of electric current. And when an electric current is passed through a wire it produces magnetic field around it, this is called magnetic effect of electric current.

There are several factors influencing the rate of corrosion including diffusion, temperature, conductivity, type of ions, pH value and electrochemical potential.

Answer 2

Answer:

12.magnetic effect of electric current: the display of behaviour/ properties, similar to that of a magnet by a current carrying wire/ coil.

heating effect of electric current: production of heat in a wire/ coil due to the flow of an electric current
