How do i know which hFE value to use from a bc548 npn transistor data sheet for biasing the base to get the required current on the collector that is controlled by base current ?
For example if its 100 gain i choose resistor input 1 ma into base and get the expected 100ma on the collector-emitter junction?
Does base-emitter voltage change or remain consent at around .6v,.7v?
Does hFE gain change or remain constant in a bipolar npn transistor?
