Lesson: Electric Fields Physics

Students will be able to

• recognize and draw the field lines for the electric field produced by static positive and negative electric charges,
• recognize the field lines for the electric field produced by two static charges that are near to each other,
• recognize and draw the field lines for a uniform electric field,
• recall that the arrows on field lines indicate the direction of the electric field,
• recall that where field lines are closer together, the electric field is stronger,
• recall that electric field lines indicate the direction in which a positive test charge will move,
• recall that a negative test charge will move in the opposite direction to the field lines of an electric field,
• recall that a large, flat, charged sheet will produce an almost uniform electric field above it and below it,
• recall that two oppositely charged, large, flat plates positioned parallel to each other will produce a roughly uniform field between them.
