__**June 9, 2011**__ Ohm's Law Simulation 1) Go to the following website [] 2) Run simulation 3) Create a series circuit using whatever components you wish. Measure the voltage and current of your circuit and determine whether or not it obeys Ohm's law. Note: The circuit is not working until the electrons begin to flow. 4) Alter the resistance of the light bulb and record how it impacts the current and voltage 5) Alter the voltage and determine how it impacts the current and resistance

When you are finished, try completing the following tasks:

1) Make a light bulb light brightly using 4 batteries. 2) Add an on/off switch. 3) Make 3 light bulbs light brightly with all 3 with the same brightness (same current, measures the same number of amps). 4) Have a switch that turns on/off 2 of the 3. 5) Have a switch that turns on/off all 3 lights. 6) Make a circuit with one main on/off switch that will turn on/off 3 bulbs, each with a different brightness. Use the non-contact Ammeter to check for different currents. 7) Change the circuit so 1 switch will turn on/off all the lights and a second switch will change the lights from all being the same brightness to all being different brightnesses.
