bimetallic strips explain answer
Answers
Explanation:
A bimetallic strip consists of two different materials with different expansion coefficients that are bonded together.
When the bimetallic strip is cooled, the metal-A contracts more than the metal-B. Then the bimetallic strip bends with the metal-B on its outer side. When a thermostat is used in an electrical circuit, its bimetallic strip gets heated and bends if the temperature in the circuit exceeds a certain limit.
Answer:
Bimetallic strip is a strip that is made up of two different strips of different metals which are joined together. When this strip gets heated, it bends due to unequal expansion of the two different metallic strips. Then, on cooling the bimetallic strip gets bend in the opposite direction.
These bimetallic strip is being used in various devices like refrigerator, bimetallic thermometer, etc.
