hi,
been a way from electronics for a long long time, im trying to build a circuit to switch on relays and leds, cant remember how to work out the base current of a tranny resistor?, can someone please remind me also in the speck sheet what value is the base current? my circuit, (i cant seem to post a link of the sheet) its a sm sot-23
ok had another long look am i right in saying Ic is the collector current if so in the speck sheet it says 100 im asuming this is 100ma? so you use ohms law to work out the resistor? using a 5v to the base of tranny
am i correct in saying 50 ohm resistor
thank you
