Homework Statement The equivalent capacitance of the capacitors shown in the figure is 9.26 uF http://session.masteringphysics.com/problemAsset/1122585/1/Walker.21.58.jpg Homework Equations Cseries = 1/Cs = 1/c1 + 1/c2 + ... Cparallel = Cp = C1 + C2 + ... The Attempt at a...

Here it is: 1/Req1 = 1/55 + 1/R = 1/55(R/R) + 1/R(55/55) = R/55R + 55/55R = (55+R)/55R Req1= 55R/(55+R) 12 + 55R/(55+R) = 27 12 + 55R = 27(55+R) 55R = (27-12)(55+R) 55R = (15R) + (15 x 55) 40R = 825 R = 20.625

Thanks for the help tiny-tim! :biggrin: I ended up getting 21 Ω which turned out to be right :D

Homework Statement The equivalent resistance between points A and B of the resistors shown in the figure is 27Ohms. Find the value of resistance R. Here is the diagram: http://session.masteringphysics.com/problemAsset/1122575/1/Walker.21.36.jpg Homework Equations Rseries =...

Hello, first post. I hope that someone can help me with this. I will roughly summarize the problem, and what I've done thus far. Homework Statement A lady was in an elevator that free-fell 6 feet and abruptly came to a halt. We had to determine a reasonable best case and a reasonable worst...
