Jim stirred and pulled his transistor from his pocket, unplugging the earphones, so that the oldies overrode Jake's snoring

We should recall what is transistor from previous section, Transistor is a very important component in modern day electronics
3.
transistor shuts off when no voltage is applied to collector-base and LED goes off
4.
Transistor is a polar device and should be connected in correct direction of current
5.
The arrow in transistor symbol shows the direction of flow of current, In NPN its from collector to emitter and in PNP its from emitter to collector
6.
The LED in this circuit flashes alternatively because each transistor is switched On and Off in turn due to C1 charging and discharging through R2 and C2 doing same through R1

In electronics, the Darlington pair is a compound structure consisting of two bipolar transistors connected in such a way that the current amplified by the first transistor is amplified further by the second one
11.
This configuration gives a much higher common-emitter current gain than each transistor taken separately
12.
transistor leads are not touching each other where they come out of the bottom the
