If a Bimetallic strip is heated it will
bend towards the metal with lower thermal expansion coeffient
bend towards the metal with higher thermal expansion coefficient
not bend at all
twist itself into a helix
As we learned
Bimetallic Strip -
Two strips of equal length but of different materials when joined together are called Bimetallic strip.
- wherein
If heated bimetallic strip will bend towards the metal with a lower thermal expansion coefficient i.e., metal with a lower thermal expansion coefficient will be on the concave side.
