Answer 1

Answer:

e)

Question:-

• Electroplating is based on magnetic effect of electricity.

Answer:-

• It's incorrect sentence
• As we know that, while electroplating there are two rods, one becoming cathode and another one becoming anode. During electroplating, when electricity is given through the rods, the anode produces positive ions which gets received at the cathode rod and negative ions produced at cathode collects at anode rod which results to the plating of the desired substance. Here, it is a chemical effect of electricity resulting to plating.

So correct sentence is:

• Electroplating is based of chemical effect of electricity.

f)

Question:-

• An electric bulb glows due to the chemical effect of electricity.

Answer:-

• It's incorrect sentence
• As we know that, in an electric bulb there is a filament. When electricity is given in that filament of the electric bulb, the filament gets intensely heated up and results to the emission of light. Due to this heating of the filament due to electricity the electric bulb glows.

So correct sentence is:

• An electric bulb glows due to the heating effect of electricity.
