Which of the following is NOT an example of the heating effect of current?

Correct option is B

The correct answer is (b) Working of a fan.

• The working of a fan is based on the magnetic effect of current, where electric current passes through a motor winding, creating a magnetic field that causes the rotor to spin and thus the fan blades to rotate.
  
• The other options, a bulb, electric iron, and electric kettle, are all based on the heating effect of current.
  
• In a bulb, electric current passes through a filament, heating it up until it glows and emits light.
  
• An electric iron uses electric current to heat up a resistive element, which is then used to iron clothes.
  
• An electric kettle heats water by passing current through a heating element submerged in the water, causing it to heat up and boil.

Information Booster:

• Bulb: Utilizes the heating effect of current to make the filament glow and emit light. It is a common example of converting electrical energy into light and heat.
  
• Electric Iron: Uses the heating effect of current to heat a resistive element, which in turn heats the base plate for ironing clothes.
  
• Electric Kettle: Heats water by passing current through a heating element, converting electrical energy into heat to raise the water's temperature.
