hi pls help

[Anushya]

in a BC 549 and BC 547 transistor i want to know which is the emitter,base and collector.

also in a HO 4R infra red dual type sensor i want to know the transmitter part (diode)which is the anode and cathode...and in the receiver part(transistor)which is the emitter and collector?

Putting your email address in a public forum is a REALLY REALLY BAD idea. Spambots crawling the web will pick it up and load your inbox with all manner of unpleasnt stuff. You should at least replace the @ symbol with __AT__ or some such artifice.
