Textbook Question
Chapter 6.1, Problem 1bT
A student has briefly connected a wire across the terminals of a battery until the wire feels warm. The student finds thatthe wire seems to be equally warm at paints 1, 2, and 3.
Based on this observation, what might you conclude is happening in the wire at one place compared to another?

Which of these lightbulbs, the 25-W bulb (upper left) or the 60-W bulb (upper right), has the higher resistance? Which draws more current? Which uses the most energy? Can you tell from the color that the 25-W filament is cooler? Is the brighter bulb a different color and if so why? (credits: ickbauch, Wikimedia Commons; Greg Westfall, Flickr)
Why does a wire that carries electric current become hot?
What is the differance between Conductors and Insulators ?
