Electric fields

How do electrons behave in conductors and insulators

Conductors have lots of free electrons, whereas insulators do not have any free electrons

What does the direction of a field line represent in an electric field

The direction a positive test charge would experience a force

What is the field diagram for 2 oppositely charged plates

(typically drawn with parallel equidistant lines with no edge effects)

Field for 2 oppositely charged particles

Electric potential at a point definition

Where the work done to move a positive charge from infinity to that position

How can electrons be transferred from one object to another

Rubbing them together transfers energy to the electrons by friction so they can move between the objects

What is the gradient of a potential-distance graph

-E field strength
