Day 13 Electric Potential 04/14/2014

Electric Potential Lab:

This is a lab mainly focus on the potential difference between two points, and as we know the changing of voltage will give us work as long as we know the q. On this lab, power supply is 15 V, and the potential difference between two aluminum paints are 15.54 V. However, random two points on same aluminum paint is always zero, so it means there is no work require to move on this aluminum conductor. 

These is the potential difference on each displacement, and also their increment ratio;however, we increase distance 1 cm each time.

Next

Calculated the work to move a given charge:

a) x = 0cm to x = 3cm

b) x = 4cm to x = 6cm

c) x = 5cm to x = 2cm

Result

First one q = 1 so it's differential potential energy are there work , then rest can be found by the picture above. 

This is potential vs position graph, and it shows when distance increase the potential energy increase. I think it is pretty similar to work, which longer distance given bigger energy.
