Alfred Powell Morgan’s first, second, third and forth books of radio and electronics where once among the most loved beginning electronics hobby books. A motivated tween could build the projects with minimal mentoring. Building these same projects today requires assistance from a mentor with substantial vintage part acquisition and substitution skills.

Simon: hello,
delabs: hello
Simon: we have many meanings for saturation,
delabs: means turning on, also means no longer linear, or it is got fixed up, not varying in accordance to any formula
Simon: that is what is concluded of. but we just wanted to be sure.
delabs: like you put salt in water. after some time no more salt can be dissolved, that is the state of saturation, In Electrical, no more relationship with V - I - R. Any increase in voltage or reduction it is same
Simon: thanks
delabs: anytime
Bipolar transistors are so named because their operation involves both electrons and holes. These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material; electrons are majority charge carriers in n-type semiconductors,
Chapter 5: Bipolar Junction Transistors
"Saturation also implies that a large amount of minority carrier charge is accumulated in the base region. As a transistor is switched from saturation to cut-off, this charge initially remains in the base and a collector current will remain until this charge is removed by recombination."
Lessons In Electric Circuits - Bipolar Transistors
When a transistor has maximum current through it, it is said to be in a state of saturation (fully conducting).
