Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- The bimetallic strip is used by the thermostat of many devices like electric iron.
- The bimetallic strip is made up of two different types of metals (brass and iron) with a different coefficient of expansion bonded together.
- Hence in the presence of heat, the bimetallic strip expands differently. The metallic strip is connected to a contact spring through small pins. So that the temperature setting for a bi-metallic strip can be changed by moving it close and away from a heating element
- The bimetallic strip remains in physical contact with a contact point at a moderate temperature. However, at a temperature of the iron above a certain limit, the strip tends to bend towards the metal with a lower coefficient of expansion. At this point, the strip stops to be physically connected to the contact point and current stops flowing because of an opening of the circuit.
- Position (a) is when the iron is at a normal temperature.
- Position (b) is when the iron becomes too hot.
