QUOTE(zybler @ Oct 25 2005, 11:31 PM) Where was it? How do I go there? Is that a street name? It's a strict name at Pudu district. Please don't mess up between Pudu and Puduraya. Stitchy® w/o stitches |

During my training, I came across several soldering techniques like wave soldering, manual soldering and etc. These terms appear in the datasheets.
Any sites to go to have a brief idea on what are them? Stitchy® w/o stitches |

Never come across that. Just heard about negative temperature coefficient in Ohm's Law.
Perhaps superconductor might behave like that. Interested to know about this too ... This post has been edited by David83: Apr 6 2006, 09:45 PM |

QUOTE(charge-n-go @ Apr 6 2006, 09:47 PM) My fren tried, but not really working Share with us regarding the 0 resistance too.  nvm, i'll try another method. thx everybody for helping. i only learnt about 0 resistance, which happens to superconductor at very very low temperature. -ve resistance? i need somebody to enlighten me too  |

QUOTE(harrychoo @ Apr 6 2006, 10:10 PM) i think there is no such things as negative resistance. Ohm's Law is a very primitive law and the introduction of superconductor somehow violates it.if it really exist, i think Ohm's Law or other related laws won't hold anymore..lol QUOTE(charge-n-go @ Apr 6 2006, 11:22 PM) hahaha, i think we learnt a bit too in physical electronics. I oso forgotten liao Negative differential resistance is something like negative temperature coefficient. The resistance of a material decreases when a controlled variable is being altered.Negative differential resistance means, the resistance value is decreasing over time mah, rite? 0 resistance is ideal, and super conductors only has very very near to zero resistance. -ve resistance is like..... the object exist to have some energy supply (instead of resisting, it is giving energy). |
