Electrical fields
Pushing charges
A region of space that accelerates charged particles is said to have an electric field
A force will be exerted on a charged particle when it is within that field, to visualize this we draw
electric field lines. These show the direction a positively charged particle…

Equipotentials
Points within an electric field which have the same potential can be connected by lines called
equipotentials. The field will always be perpendicular to the exponential lines, as a field is defined
as a region which changes potential.
Field lines never cross.
The distance between equipotential lines tells you…
