Electric Fields

1. Electric Fields and Potential

• electric field lines
• electric field vector
• Between any two equipotential lines, the average electric field is equal to

2. Electric Fields and Force

• $\overrightarrow{F}=q_T\overrightarrow{E}$
• Positive targets feel a force with the electric field.
  Negative targets feel a force against the electric field.

3. Single Source Charge

• $\overrightarrow{E}=k\frac{\left|q_S\right|}{r^2}\{\begin{array}{ll}\mathrm{a}\mathrm{w}\mathrm{a}\mathrm{y}& \mathrm{i}\mathrm{f}{q}_S>0\\ \mathrm{t}\mathrm{o}\mathrm{w}\mathrm{a}\mathrm{r}\mathrm{d}\mathrm{s}& \mathrm{i}\mathrm{f}{q}_S<0\end{array}$

4. Multiple Source Charges

5. Electric Field Lines
