Chapter 21

Key Ideas:
1. Like charges repel, opposite charges attract.
2. A shell of uniform charge acts on any charge outside the shell as though the shell were a point charge concentrated at its centre.
3. A shell of uniform charge exerts no net force on any charge inside the shell.

Key Ideas:
1. Filed lines originate in positive charges and terminate in negative charges.
2. The electrostatic acting on a charge is in the direction of the field if the charge is positive and opposite if the charge is negative.

Key Ideas:
1. The net flux through a closed surface is zero if there is no enclosed charge.
2. In a conductor, any net charge will be on the surface of the conductor. The field in the body of the conductor will be zero.
3. The field near a charged conducting sheet is twice that near a charged non-conducting sheet.

Chapter 24

Key Ideas:
1. Positive electrical potential is like a "hill" for positive charges; i.e. they will run down.
  Negative charges will run up.
2. Calculating potential can be done by a scalar integral or a path integral of the field.
  One way will usually be much easier than the other.
3. The electric field points in the direction of steepest drop of electrical potential; i.e. it is the negative of the gradient of the potential.
4. Work done in moving a charge is the charge times its change in potential.

Chapter 25

Key Ideas:
1. Capacitors in parallel add.
  In parallel, capcitance increases.
2. Capacitors in series add reciprocally.
  In series, capcitance decreases.
3. To solve circuits with multiple capacitors, redraw to clarify which capacitors are in series and which are in parallel.
4. To solve circuits with multiple capacitors, determine equivalent capacitance step by step until you know charges and voltages, then work backwards.

Chapter 26

Key Ideas:
1. The direction of current flow is based on the assumption of positive charge carriers.
2. Resistivity is a material property; resistance is a device property.
3. A device is called ohmic if current and voltage are always in the same ratio.
4. Power dissipation (or production) in a device is the product of current and voltage.
