Document Summary
20. 1 electric potential energy in a uniform electric field. Use electrical potential energy in problems involving uniform electric fields. Describe the motion of a charged object when it moves (or is released from rest) in a uniform electric field. Solves problems involving electric potential energy, electric potential, and potential difference in a uniform electric field. Define electric current, and its si unit, and solve related problems. State the direction of motion of electrons and its relation to the direction of electric current. Discuss some dangers dangers associated with electric current and voltage. Suggested problems: ch 20: 3, 4, 5, 6, 9, 10, 13, 20, 21, 22, 23, 27, 28, 42, 43, 44, 45, 47, 51, 52, 53, 54, 55 ch21: 1, 2, 6, 9, 13, 14, 15, 16, Q3a) a typical fair- weather electric field near 1. 5 x 10 raised to the power 2 n/c downward. Si force n n/c = newtown / coulomb.
