## 소개글

There is some measuring variations in charge density although we measure just one object. The reason is easy, because of it`s electric field - as the charge moves until the electric field becomes zero, there are some difference in surface charge density. Generally, it is bigger than other place when it is more sharper than. To prove this things, we experimented about it. In addition, we had an experiment about making electric field map.

2.1 Electric field
In physics, the space surrounding an electric charge or in the presence of a time-varying magnetic field has a property called an electric field. This electric field exerts a force on other electrically charged objects. The concept of electric field was introduced by Michael Faraday.

2.2 Electric Potential and Equipotential Lines
Electric potential is the potential energy per unit of charge associated with a static (time-invariant) electric field, also called the electrostatic potential, typically measured in volts. It is a scalar quantity.

[1] We can find out the resistance of copper wire by measuring the voltage and current. In this case, we should pay attention to the resistance of the wire that we used to connect the copper wire to the power source.
