... A certain portable television was found to have been left on. It was powered by six brand new DCells in series making a 9 volt battery. Each D-Cell has a rating of 1 amp-hour and the initial power supply is 4.5 W. (A) What current did the battery supply? (B) How long was the television on? (C) What ...

For example: an electric iron draws a current of 4A at 250V. What
... You can place a bar magnet underneath a sheet of white paper and sprinkle the iron filings on top of the paper. Gently tap the paper. The iron flings align themselves with the magnetic field and the pattern of the force fields can be seen (although it is not all that convincing) Alternatively you ca ...

... Synthesis: Ingots (~6 g) of Pb0.60-xKxSn0.40Te (x = 0.0, 0.01, 0.02, 0.03, 0.04) were synthesized by mixing appropriate ratios of high-purity elemental Sn, Pb, K and Te in carbon coated quartz tubes. The tubes were sealed under vacuum (10−5 Torr) and slowly heated to 723 K over 12 hrs, then heated u ...
