Demonstrate how a bimeallic strip works in a thermostat?​

Answer»

A TRADITIONAL thermostat has two pieces of different metals BOLTED TOGETHER to form what's called a bimetallic strip (or bimetal strip). ... When the strip gets hot, one of the metals EXPANDS more than the other so the WHOLE strip bends very slightly. Eventually, it bends so much that it breaks open the circuit.
