Glossary
Electric Field: A region of space around a charged object where other charges experience a force.
Electric Force: The force exerted by a charged object on another charged object.
Field Strength: The force experienced by a unit positive charge in an electric field.
Potential Difference: The work done to move a charge between two points in an electric field.
Theory
Electric fields are created by charged particles. The strength of an *electric field* depends on the charge and distance from the source. The electric field () strength is calculated using the formula:
E = F/q
Where:
- *E* is the electric field strength,
- *F* is the force exerted on the test charge,
- *q* is the magnitude of the test charge.
The direction of the field is determined by the direction of the force experienced by a positive charge.
Key terms include , , and .
