In metals, the outer most electron of each atom is unaccented attracted to the positive nucleus and can escape from the atom and stack around mingled with 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 you connect the piece of metal across a stamp battery all these electrons are still whizzing close at random, only they are also coerce to slow 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 carry-forward energy to them. This is where the pronounce resistance comes in. The electrons experience resistance to thei...If you pauperization to get a full essay, order it on our website:
