I know that may appear like a really stupid question but what mean these two symbol? Thanx!
An externally hosted image should be here but it was not working when we last tested it.
qwad said:first one is a transistor[ not sure if a pnp /npn] ....
there is some mnemonic for this...I THINK it's this:
NPN is 'Never Points iN
PNP is 'Points iN Perpetually
someone please correct me if i am mistaken. i'm not an EE guy, i just read a basic textbook recently.
/andrew - dammit jim, i'm an architect, not an electrical engineer!
Transistor and Pot
Its a NPN transistor and a variable resistor or trimmerpot. Pot being short for potentiometer.
Page 61 a.f. in Horowitz. Have you searched H.??

"A transistor is a 3-terminal device (Fig.2.1) available in two flavors (npn) and (pnp) with properties that meet......."
BTW I am a bloody chemist.
qwad said:first one is a transistor[ not sure if a pnp /npn] second is an adjustable resistor for setting bias etc, along with its value, ppl with more knowledege than me, will correct me if I am wrong; cheers Tomcat
