Name From sidem.com Philateractives httpswww.physicsclassroom.com/Physics Interactive Electric Circuits Circuit Builder Circuit Builder-Interactive DC Circuit Builder Series Circuit Goal: To analyze mathematical relationships between quantities for series circuits. Getting Ready: Using your computer, tablet or phone and navigate to: http://goo.gl/M4Ewmh Tap or click the link to open the DC Circuit Builder. Once opened, select the pencil icon and use the tools (at the bottom of the screen) to build a circuit. Simply select a bulb, resistor, wire or ammeter (the rectangular box) and tap or click in the workspace where you wish it to be located. You'll get the hang of it quite quickly. Note that the electric potential values are listed on the diagram at the corner of every square on the grid. Current values are listed on the ammeters. To change a battery voltage or a resistor value, select the second icon at the bottom of the screen; a magnifying glass appears above the circuit element. Adjust the voltage or the resistance using the up/down arrows next to the digital meter Build, Measure, Analyze: Build the circuit shown with three resistors, four ammeters and a battery. Determine the values of current (amps) and electric pressure (volts) at the indicated locations. V= Amps Volts Volts 2 Amps Ampo Valts 1. Amps V=--Volts For resistors 1, 2, and 3 and for the battery (B), calculate the electric potential difference and fill in the table below. Element Electric Potential Current (1) Resistance (R) Difference (AV) B 1 2 3 2. How does the current in each resistor (I., 13, 1) compare to one another and to the current in the battery (I.)? How does the electric potential difference across the battery (AV) compare to the summative electric potential differences of the three resistors (AV, + AV, + AV,)? 3. 4. Write the above relationship as an equation: 5. Calculate the ratio of electric potential difference to current for the battery. AV/Ig = How does this ratio compare to the resistance values of the resistor? Attempt to write an equation relating the AVg/Ig ratio to R1, R2, and R, values. 6. Alter the values of the battery voltage and the resistance of the resistors so that each resistor has a different resistance. Then make measurements and complete the table. Electric Potential Element Difference (AV) Current (1) Resistance (R) B 1 2 3 7. Using values from the circuit analyzed in Question #6, identify as many mathematical equations as you can that relate AV, I and R for individual circuit elements or for the circuit as a whole. For each equation that you write, demonstrate its validity by substituting in values from the table above. Equation Demonstration of Equation's ValiditY
