Study Notes
Electrostatic Force
- Electrostatic force is the attraction or repulsion between electric charges
- Coulomb's law can be used to calculate electrostatic force (F = kQ1Q2/r^2)
- Q1 and Q2 are the charges, r is the distance, and k is a constant
Electric Field and Representation
- An electric field is a region where a charge experiences a force
- The electric field is a measurable effect from a charged object
- Electric fields always coexist with charges
- Electric fields can be used to predict charge behavior
- Mathematically, the electric field (E) can be calculated using E=kQ/r^2
Source and Test Charge
- Source charge (Q) creates the electric field
- Test charge (q) is used to measure the effect of the source charge's field
- Source charge is always positive
- Positive test charges are attracted to negative charges and repelled by positive charges
- Negative charges have field lines drawn toward them
- Positive ones have field lines drawn away
Electric Field Lines
- Electric field lines graphically represent the electric field
- Density of lines shows field strength; more lines mean a stronger field
- Field lines are closer together in stronger fields
Electric Potential
- Electric potential is the electric potential energy per unit charge
- Equivalent to work needed to move a charge between points
