Chapter 20, Problem 20.13(choose chapter or problem)
The drawing shows a circuit that includes a bimetallic strip (made from brass and steel; see Section 12.4) with a resistance heater wire wrapped around it. When the switch is initially closed, a current appears in the circuit because charges flow through the heater wire (which becomes hot), the strip itself, the contact point, and the light bulb. The bulb glows in response. As long as the switch remains closed, does the bulb (a) continue to glow, (b) eventually turn off permanently, or (c) flash on and off?
