A Nichrome heater dissipates 500 W when the applied potential difference is 110 V and the wire
Question:
A Nichrome heater dissipates 500 W when the applied potential difference is 110 V and the wire temperature is 800°C. What would be the dissipation rate if the wire temperature were held at 200°C by immersing the wire in a bath of cooling oil? The applied potential difference remains the same, and α for Ni chrome at 800°C is 4.0 x 10-4 K-1.
