Study Notes
Electric Field
- An electric field is a region of space where a charge will experience an electric force.
- The direction of the electric field is the direction of the force exerted on a positive charge in the field.
- The electric field is radially outward from a positive charge and radially inward toward a negative charge.
- The closer a test charge is to the source charge, the greater the force it will experience.
Comparing Electric Field and Gravitational Field
- Source:
- Electric fields are generated by electric charges.
- Gravitational fields are generated by mass.
- Type of force:
- Electric fields can produce both attractive and repulsive forces, depending on the charges involved.
- Gravitational fields only produce attractive forces.
