Notes on Chapter 33

Electric Fields & Potential

“May the FORCE be with you”

electric fields potential1
Electric Fields & Potential
  • All particles have an electric field around them.

A electric field is a kind of aura that extends outward through space.

electric fields potential2
Electric Fields & Potential
  • To show the effects of the electric field, we use a “small test charge” (which is positive) to determine the direction and strength of the field.

  • To show the effects of the electric field, we use a “small test charge” (which is positive) to determine the direction and strength of the field.

Electric Fields & Potential
  • Since the field has magnitude and direction it is

a vector and can

be represented

with vectors.

  • These vectors are called Field lines or Lines of force
      • (See fig. 33.3 pg. 519)

  • Where these force lines are close together, the force is strong. Where the lines are farther apart, the force is weaker.

Electric Fields & Potential

Electric Shielding:

  • Because of mutual repulsion, electrons move as far apart as possible. On a hollow object, the interior will have NO CHARGE OR FIELD. The force on a test charge inside a hollow sphere will cancel to Zero
electric fields potential8
Electric Fields & Potential
  • On odd shaped objects, the chargeinside is still zero, but not uniform on the outside.

Electric Potential Energy:

  • Remember chapter 8 when you lifted an object --- you did work on that object. The same thing applies here.
  • A test charge has

Potential Energy by

virtue of its position.

  • If the test charge is “let go”, the potential energy will be transferred into kinetic energy of movement.

Electric Potential = Electric potential energy

Charge

1 Volt = 1 Joule_____

1 Coulomb

  • Note --- The voltage of a balloon rubbed on your head can be very high. But the electric potential energy is low because of the small amount of charge.

Storage of Energy:

  • Electrical energy can be stored in a common device called a capacitor.
electric fields potential13
Electric Fields & Potential
  • A capacitor is a devise that has two plates separated by a small distance and connected to a battery.
      • Note --- this can be a Shocking experience if you are the discharging path !
