G) Electric Field - region in space where electric forces act on charges
Did you know that sharks can 'see' electric fields.

1) vector quantity
2) E = F/q (on reference)
E = Electric Field Strength
(N/C)
q = amount of charge
F = force on charge
3) The direction of an electric field is drawn to show how the field acts on positive charge (Decided by convention)
Electric Field Patterns
Spherical Charges
| a)positive charge | b)negative charge |
 |
 |
| ou+ | in |
Radial Fields
Field at the center of a charge = zero
| c) 2 opposite charges |
 |
| d) 2 like charges |
 |
e) Field between a positive and neutral charge
f) Field Lines between opposite charged parallel plates
** Field between plates is uniform
- (same strength all over)
