Chapters 19-20 WebLab#1 “Resistors” Ravikumar Ashok, Per. 4 * Go to the following website: http://lectureonline.cl.msu.edu/~mmp/kap20/RR506a.htm * Click on the “Two, Series” button and observe the arrangements of resistors and the overall “equivalent resistance”. * Use the slider bar at the upper right to change the resistance of one of the components. Note how the equivalent resistance changes. * Repeat for each of the six arrangements. Questions: 1) For resistors in series, how are the individual resistances related to the equivalent resistance? The sum of the individual resistances is equal to the equivalent resistance. 2) What effect does increasing one of the resistance values have on the equivalent resistance of a series arrangement? The equivalent resistance increases when one of the resistance values is increased. 3) For resistors in parallel, how are the individual resistances related to the equivalent resistance?

Unformatted text preview: The sum of the reciprocals of the individual resistance values is equal to the reciprocal of the equivalent resistance value. 4) What effect does increasing one of the resistance values have on the equivalent resistance of a parallel arrangement? The equivalent resistance increases when one of the resistance values is increased. 5) If you have resistor R 1 = 20 Ohm and resistor R 2 connected in series, what are the minimum and maximum equivalent resistance values that are possible? The minimum equivalent resistance value is 21 Ohm, and the maximum equivalent resistance value is 119 Ohm. 6) If you have resistor R 1 = 20 Ohm and resistor R 2 connected in parallel, what are the minimum and maximum equivalent resistance values that are possible? The minimum equivalent resistance value is 0.9523 Ohm, and the maximum equivalent resistance value is 16.638 Ohm....
