The conservation of energy covers all types of energy. This lesson has only provided a handful of examples of it. To be more convinced that it works in another context, devise an experiment to evaluate the conservation of energy. Describe your setup and the data you would need to collect

Copper has free electrons per cubic meter. a 71.0-cm length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 a of current. (a) how much time does it take for an electron to travel the length of the wire? (b) repeat part (a) for 6-gauge copper wire (diameter 4.12 mm) of the same length that carries the same current. (c) generally speaking, how does changing the diameter of a wire that carries a given amount of current affect the drift velocity of the electrons in the wire?
