Name _________________________________ Date ___________ Lab Section M W F Answer each of the questions and turn this in to me by Monday, March 17 th at 330 pm. If you cannot make it to class, then you must email it to me by the beginning of class. 1. What are 3 characteristics of a series circuit and what are three characteristics of a parallel circuit? A series circuit has all of the current flows through each device, the magnitude of current does not change, adding a resistor increases resistance, voltage across lights/devices is split up, and if one goes out all go out. A parallel circuit has current slip up among the paths, voltage is same across devices, adding a resistor decreases total resistance, and if one goes out the others stay on. 2. Draw the field lines for the following situation: A sphere on the left has a magnitude of charge of + 5 q. A sphere on the right has a magnitude of charge of – 3 q. 3. Evaluate the following statement:

Unformatted text preview: 50,000 volts coursing through your heart can kill you. The resistance of ones body depends on the condition, how wet or dry it is. Current=Volts/Resistance (ohms), so a wet body has less resistance, but if it is dry it has high resistance and might not kill it. 4. Explain why the happy ball was able to knock over the plank and not the sad ball in this video: http://paer.rutgers.edu/pt3/experiment.php?topicid=4&exptid=140 . The happy ball is lighter, more momentum. The sad ball is heavyer and does not bounce. Bouce creates the reaction on the board every action has an equal & opposite reaction. The bigger bounce has a bigger force on the board. Elastic collision- momentum is transferred from the happy ball to the board knocking it down. 5. A 12 volt battery provides how big of a current through a 6 Ohm resistor? Current=Volts/Resistance(Ohms), Current=12/6 Current=2...
