- A Certain Heating Element Is Made Out Of Nichrome Wire And Used With The Standard Voltage Source Of V 120 V Immediately 1 (56.7 KiB) Viewed 44 times
A certain heating element is made out of Nichrome wire and used with the standard voltage source of V=120 V. Immediately after the voltage is turned on, the current running through the element is measured at I1=1.67 A and its temperature at T1=25∘C. As the heating element warms up and reaches its steady-state (operating) temperature, the current becomes I2=1.553 A. Find this steady-state temperature T2 : T2= z. What would be power P3 consumed by this heating element if its operating temperature was T3=300∘C ?: P3=kW. To make things certain, let us use nominal temperature coefficient of resistivity α=4.0×10−4(∘C)−1 for Nichrome.
