Circuits à Resistance in a Wire As wire length (cm) increases, the resistance (22) As wire area (cm) increases, the resistance (22) As wire density (cm) increases, the resistance (12) Procedure Part II: Ohms Law: Electricity, Magnets, and Circuits à Ohm's Law VISIT THE SITE: https:/phet.colorado.edu/en/simulation/ohms- law .mA is milliamps, and milliamps equals one Ampere. - Move the potential (volts) and resistance (ohms) sliders and observe the current (amps) As voltage increases, current As resistance increases, current Fill out the tables below and check your work in the simulation.( 12 pt each) Remember, the simulation shows milliamps. . You should show Amperes V I R A[800 SOV 2.0 V1.044 A V10058 A 430 V1.069 A 100 6.4 V A 300 Conclusion Questions: 1. Incandescent light bulbs have a very thin filament that glows when hot. Thin filaments have very high / low resistance. 2. The 12V battery in your car operates a 25 amp car stereo. What is the resistance of this stereo system? 3. A2D" Maglite flashlight runs on 3.0V. What is the current through the bulb if resistance is 1522? 4. How many volts must an iPod charger provide to charge an iPOD using .85 Amps at 35 22? 3. You need to buy a long extension cord to power a stereo at your spring break BBQ. You need 200feet. You have a 50 ft cord that will work. You rationalize that four such 50 ft cords will do the job. Is this a good idea? Why or Why not?
