Homework Statement Two resistances, R1 and R2 are connected in a series circuit across a 12V battery. The current increases by 0.20A when R2 is removed leaving R1 connected across the battery. However, the current increases by just 0.10A when R1 is removed, leaving R2 connected across the...

Ok lol. Yeah, I thought your posts was familiar. Thanks for the help, but the Voltage wasn't given in the problem. Your method totally makes sense, but when I solve for V and replug it into the original equation I get 20 deg C, when it should be 360 deg C.

^Did you post on yahoo answers? Well anyways, no voltage was given and the answer is 360 degrees.

Homework Statement A toaster uses a Nichrome heating wire. When the toaster is turned on at 27 deg C, the initial current is 1.50A. A few seconds later, the toaster warms up and the current is now 1.30A. The avg. temp coefficient of resistivity for Nichrome wire is 4.5 x 10 ^ -4 (degree C) ^-1...
