resistence basic guide A basic guide to resistance. electron Flow Model Everything is made of very small particles called atoms. individually atom has a heavy positively charged centerfield and is surrounded by a cloud of light, negatively charged, electrons. In metals, the outer most electron of each atom is exhausted attracted to the positive nucleus and can escape from the atom and pip around surrounded by 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.
W hen you connect the piece of metal across a stamp battery all these electrons are still whizzing some at random, only they are also coerce to easily 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 conveyance energy to them. This is where the pronounce resistance comes in. The electrons experience resistance to thei...If you indigence to get a full essay, order it on our website:
