9. A 1500 W heating element at an initial temperature of 15°C is connected to a supply voltage of 115 v. After the temperature of the element has been stabilized (steady- state conditions), it is found that a voltage of 125 volts is required to maintain rated output. If the temperature coefficient of the element is 0.0006 per •c, determine the element's final temperature. e. 300°C 1. 205°C g. 290°C h. 317°C 10. Calculate the length of the copper wire having a diameter of 1/16 inches and resistance of 2 ohms.
