6. Example Job

7. Solution Sheet P=45w V=120v R=? P=VI I=V/R P=V 2 /R Ohm’s Law V=IR And Power P=VI Given to students 45=120 2 / x x=120 2 / 45 R=320Ω 7

8. Grading

9. Grading a Solution P=45w V=120v R=? P=VI 45=120 2 / x x=120 2 / 45 R=320Ω R=320 10% 7 30% 20%+0% Total: 80% Earned: 900$*.8 = 720$ Missing an Equation Missing Units

10. Grading Modifications Groups can pay for perks Check a solution Peace of mind Balance Spy Compare answers Instructor does the spying Hint Knowns/Unknowns
