  1. Electric Circuits Assignment • What does it mean for an object to be negatively and positively charged? When does an electric field form? • Joe seems to think that voltage is the amount of current that flows through the circuit. Is he correct? If not, please write a paragraph explaining the difference between voltage, current and resistance. • Use Ohm’s Law to prove that wet hands could kill you and dry hands might just save your life. • Wet hands resistance = 1000 ohms • Dry hands resistance = 100,000 ohms • Voltage = 120 V • Thresholds for electric current: Tingle (0.001 A), Pain (0.005 A) Loss of Muscle control (0.015 A) Possible Death (0.070 A) • Read Ch. 35.2 (pages 704-707) • Compare and contrast a series and parallel circuit that is using three light bulbs.

  2. 2nd Semester Exam • Units • Momentum, impulse and law of conservation of momentum • Work, Power and Energy • Simple Machines and Efficiency • Thermal Energy • Waves: Sound and Seismic • Electromagnetic Waves and Light • Electricity and Electric Circuits

  3. 2nd Semester Exam • Solve problems • Momentum, impulse, collisions • GPE, KE, Work, Power • Mechanical advantage, efficiency • Specific heat capacity, temperature conversions • Wave speed and frequency • Ohm’s Law

  4. Study Guide • Use the unit guide for each of the units as a study guide • Highlights • Use old tests, textbook and notes
