**Ohm's Law** The German scientist Georg Ohm worked on circuits in \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. He discovered the relationship between \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. He described this relationship \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. **[THE RELATIONSHIPS]** *First Relationship* When the resistance in a circuit \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_, the current will \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. AN ANALOGY (In an obstacle course) If you add more obstacles (\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_), the runners (\_\_\_\_\_\_\_\_\_\_\_\_\_\_) will be slower. How could this be done? - Connecting more loads in \_\_\_\_\_\_\_\_\_\_\_\_\_\_ - Connecting loads in series rather than \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. - Making a conductor \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ - Making a conductor \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ - Using a material with higher \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. *Second Relationship* When the resistance in a circuit \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_, the current will \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. AN ANALOGY (In an obstacle course) If you remove obstacles (\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_), the runners (\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_) will be faster. How could this be done? - Connecting fewer loads in \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ - Connecting loads in parallel rather than in \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. - Making a conductor \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ - Making a conductor \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ - Using a material with lower \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_. **[SEEING THIS WITH NUMBERS]**  What is the Pattern??? Load Voltage drop (V) Current (A) Resistance (Ω) ------------------ ------------------ ------------- ---------------- Light bulb (60W) 120 0.50 240 Coffee grinder 120 1.20 100 Food dehydrator 120 4.60 26 Toaster oven 120 14.0 8.6 What pattern do you notice for current and resistance when the voltage remains the same? If the current remains the same what would happen to the resistance if the voltage was increased? If the resistance remains the same what would happen to the current if the voltage was increased?
