Example: Electric Field in a Shower
When a shower is turned on in an enclosed
bathroom, the splashing of the water on the
tub can fill the room with negative ions, and
hence generate an electric field of up to 1000
N/C.

Electric Potential Energy
The electrostatic force is a conservative force
The work done moving a charge is
independent of the path taken
We can therefore assign an electric potential
energy to a system with charge.

Capacitance
A Capacitor is a device which stores charge.
The electrical device is usually some form of
parallel plate device

Energy Density
You can view the energy storage of the
capacitor as being held in the electric field E
between the plates.
The greater the volume enclosed between the
plates, the more energy can be stored.

Resistance
The Resistance of a device is defined by the
ratio of the potential applied to the current
flowing.

1.1 Purpose
The goal of the experiment is to measure a charge on an object using two instruments, the electroscope
and an electronic charge sensor. You will learn how to use the Logger Pro software to record and analyze
data.

A charged disk has a surface charge density function of () = 6 C/m2, where b is a constant.
Derive the equation for the electric field at a point P, z above the disk on the axis, assuming the disk has
