Wheatstone bridge
A Wheatstone bridge is a measuring instrument invented by Samuel Hunter Christie in 1833 and improved and popularized by Sir Charles Wheatstone in 1843. It is used to measure an unknown electrical
resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component.

I haven't touched induction in a while now, and even after reviewing a bit I still can't figure out how to even start solving this problem :
$1-\frac{1}{2}+\frac{1}{3}-\frac{1}{4}+...-\frac{1}{2n}=\frac{1}{n+1}+\frac{1}{n+2}+...+\frac {1}{2n}$

How much energy to heat a room, and heat pump efficiency?
If I am understanding correctly, thats 10 watts per sq. ft. so a 10 x 10 room would be
100 sq. ft. requiring 100 * 10 watts, or 1000 watts to maintain a "typical" temperature.
Could this also be stated as 1000 watts per hour or 1kwh to maintain room temperature?... | {"url":"http://www.physicsforums.com/showthread.php?t=279916","timestamp":"2014-04-20T21:32:06Z","content_type":null,"content_length":"29725","record_id":"<urn:uuid:9cf07fe6-bc45-404d-b3f2-ea80b6ff27bc>","cc-path":"CC-MAIN-2014-15/segments/1397609539230.18/warc/CC-MAIN-20140416005219-00126-ip-10-147-4-33.ec2.internal.w... |

Heat Engines and the Carnot Cycle
A heat engine is a cyclic process that absorbs heat and does work on the surroundings. "Cyclic" means that the system returns to its initial state at the end of each cycle so that there is no
permanent change in the system. The only cycle we will work with in this course is the Carnot ... | {"url":"http://www.chem.arizona.edu/~salzmanr/480a/480ants/carnot/carnot.html","timestamp":"2014-04-20T13:18:35Z","content_type":null,"content_length":"10927","record_id":"<urn:uuid:91e8238c-1e33-4e7a-9fb5-212375764c69>","cc-path":"CC-MAIN-2014-15/segments/1397609538787.31/warc/CC-MAIN-20140416005218-00598-ip-10-147-4-... |
