Homework Statement
Two 110-V light bulbs, one "25W" and the other "100W" are connected in series to a 110 V source. Then:
a. the current in the 100W bulb is greater than in the 25W bulb
b. the 25W bulb will be brighter
c. the current in the 100W bulb is greater than that in the 25W bulb
d. the...
ohhhhh. So in that case, the region defined by the positive slope is probably to the left of a positive test charge. The area in which there is a constant V value is at the charge and then the negative slope would be to the right of the test charge because there is lower PE the larger the x value.
ohhh so if the graph shows a positive slope then the test charge would be moving towards the positive charge and if its negative then it would be moving away?
