Please answer.. Overview: When a wire is attached to the positive terminal of a power source, such as a battery, and to the negative terminal of the battery a potential difference is set across that wire and a current is generated through that wire. Depending on how much resistance there is in the wire will affect the amount of current through that wire. Adding more resistance will further affect the amount of current.  In this experiment you will measure both the...
