Question

What is bimetal strip? Write it uses​

Answer 1

Answer:

Bimetals work with the propensity of metals to expand when heated, and contract when cooled.

• The resulting change of curvature, or bending, in response to temperature change, is a fundamental property of all thermostatic bimetals.
• In effect, the temperature change is converted into mechanical displacement.

Uses of Bimetal Strip :

• Bimetal strips are used in miniature circuit breakers to protect circuits from excess current.
• A coil of wire is used to heat a bimetal strip, which bends and operates a linkage that unlatches a spring-operated contact.
• This interrupts the circuit and can be reset when the bimetal strip has cooled down.

Answer 2

Bimetal strips are used in miniature circuit breakers to protect circuits from excess current. A coil of wire is used to heat a bimetal strip, which bends and operates a linkage that unlatches a spring-operated contact. This interrupts the circuit and can be reset when the bimetal strip has cooled down.

The resulting change of curvature, or bending, in response to temperature change, is a fundamental property of all thermostatic bimetals. In effect, the temperature change is converted into mechanical displacement.
