resistence basic guide A basic guide to resistance. negatron Flow Model Everything is made of very small particles called atoms. each atom has a heavy positively charged internality and is surrounded by a cloud of light, negatively charged, electrons. In metals, the outer most electron of each atom is colored attracted to the positive nucleus and can escape from the atom and lowlife around among the atoms. [Note 1] So, in metals, we have all these millions and millions of electrons whizzing or so at high speed, in random directions, between the situated atoms.
When y ou connect the piece of metal across a stamp battery all these electrons are still whizzing most at random, only they are also coerce to belatedly drift in one direction. This slow drift is called the current. [Note 2] As the electrons are forced through the metal they collide with the atoms and slay energy to them. This is where the pronounce resistance comes in. The electrons experience resistance to thei...If you postulate to get a full essay, order it on our website:
