That depends on the transistor, but in modern integrated circuits, a single transistor is somewhere around a hundred atoms thick; the largest atom is about 0.5 nm in diameter, so a hundred atoms would be about 50 nm. On the other hand, a typical human hair, according to Wikipedia, has a width "from 0.017 to 0.18 millimeters"; that would be 17-180 µm, which is much larger.
INTEGRATED CIRCUIT
Some transistors are as big as a bucket, and some are smaller as an average human hair's width.
Transistors are made that are smaller than a human hair. Used as part of an integrated circuit chip, which may contain thousands of transistors.

Atoms are more then a million times smaller then human hair. Hope that helps =3!!
The transistor is a replacement for vacuum tubes, which is smaller, cheaper, and more reliable for most purposes.
no, as much as people talk about revitalizing their hair, hair, by the time it exits your scalp is a column of dead cells, similar but smaller than your fingernails.
It's not an idiom that I'm familiar with. It sounds like a description - something is either literally 3 miles long and smaller than a human hair in diameter, or it is an exaggeration of something being very long and thin.
They should be, but be cautious. Some companies do advertise human hair, but it's human hair blend or human hair mixed with animal hair.
It replaces the big heat wasting vacuum tubes. They are lighter, smaller, and more sturdy.
The transistor replaced the vacuum tube, allowing radios to get much smaller and portable.
