General Science - Physics (Basics)
What is the main function of the thermostat in an electric iron?
ATo convert electrical energy into heat
BTo produce light
CTo rotate the iron plate
DTo regulate the temperature
Step-by-Step Solution
  1. Step 1: Understand the role of a thermostat

    A thermostat controls and maintains the desired temperature by switching the heating element on or off.
  2. Step 2: Eliminate unrelated functions

    Converting electrical energy into heat is done by the heating element; rotating the plate and producing light are unrelated to an iron's thermostat.
  3. Final Answer:

    To regulate the temperature → Option D
  4. Quick Check:

    Thermostat function in iron = temperature regulation ✅
Quick Trick: Thermostat prevents overheating by controlling heating element.
Common Mistakes:
  • Confusing thermostat with heating element or motor functions.
