Field around a charged sphere.

Field around a charged sphere.

1. Types of fields

   • Gravitational field
   • Magnetic field
   • Electric field

2. Electric fields

   • A charged object creates an electric field.
   • The field is always strongest closer to the object.
   • It is always in the direction of positive charge.
   • Increased charge will result in a stronger field.

3. Positive and negative charges.

   • *Arrows always have to be equally spaced to show a uniform electric field.

4. Electric fields repelling and attracting.

5. E=QV / Energy=Charge X Potential Difference (voltage)
