400. Problem 32.50 (RHK) A Nichrome heater dissipates 550 W when the applied
potential difference is 110 V and the wire temperature is
|
Solution: Click For PDF Version We recall that relation between power, P, voltage, V, and the resistance, R, is The resistance of the Nichrome wire which dissipates 550 W at 110 V will be Assuming that variation of temperature is given by the relation We find the resistance of the wire at
The dissipation rate of Joule heat at
