Question
, but a far, far better conductor than th The black paper is a conductor, not a great conductor ar beyond the edge of the paper or the cork board. Current can actually flow in the paper Outside the paper, the resistance is effectively infinite. In electrode pattern A, you had on electrode at +10V and one at ground. Thus, current flowed through the paper from the positiv o the grounded electrode and you measured the change in potential resulting from the voltage source doing work to make charges flow through the resistive paper 7. a. If you connect two +10V leads to the circul ground to the o by the DMM) of the entire conducting paper? conductor attached to a +10V voltage source and it is isolated from any other conductor by the insulating air and lab bench.) ar electrodes in pattern B and do not connect a uter conducting border, what would be the electrical potential (voltage measured V. (THINK: The paper isa b. The outer electrode is a conductor. What angle would you expect your plotted field lines Review rules on pages 3-3 to 3-5.) c. What function does the outer electrode serve in our experiment? from Pattern B to form with the rectangular siliver electrode near the edge of the paper? (HINT:Explanation / Answer
7. given
dV = 10 V
a. if we don not connect ground to the outer board and connect two 10 V leads to the electrodes
there will be net +ve charge on the apparatus
and the whole board will be at 10 V
b. electric field lines are perpenducular to the surface of electrodes
hence plotted fiekld lines from pattern B shall make 90deg angle with silver electrode on the edge of the paper
c. outer electrode serves the purpose of being the ground element ( not unless ground is not connected)
this elecvtrode collects all the +ve charge coming from the +ve electrode (i.e. this electrode suplies electrons tyhat carry the current)
