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