he drawing shows a circuit that includes a bimetallic strip (made from brass and steel) 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. If the switch remains closed, what happened to the bulb? a. continue to glow b. eventually turn off permanently c. flash on and off d. Insufficient information is given for an answer.
