A Nichrome heater dissipates 526 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 208°C by immersing the wire in a bath of cooling oil? The applied potential difference remains the same, and a for Nichrome at 800°C is 4.0 × 10-4 K-1.
