Homework Statement
https://www.dropbox.com/s/8tbqxmeoiulxg7s/Screen shot 2013-03-06 at 7.54.11 PM.png
The three light bulbs A, B, and C do not necessarily have the same resistance. The battery voltage remains constant. Click on a wire to cut that will result in the light bulb C glowing brighter. If it is not possible to do this, click in the target area. Careful, you get only 3 clicks.
Hint: Write out the formula for the current through the bulb and see what happens if one of the resistances goes to infinity. Use the methods found on the pages for parallel and series resistors.
Homework Equations
I=V/R
Resistors in series (Req = R1 + R2 + ...)
Resistors in parallel (1/Req = 1/R1 + 1/R2 + ...)
The Attempt at a Solution
On the picture you can see that there is a "x" on the wire between bulbs B and C. That is where I thought the wire had to be cut since this would remove resistors A and B, but it was wrong. I think it may be impossible to do this, but I only have two attempts left so I want to make sure I do not make a mistake again.
Thank you!
