    hi

    I have a problem with an electronics amplifiers equation. The equation is IB(base current ) = IL(peak load current)/(1+β)

    what does 1+β means?

    pls help and thanks

    beta is a parameter for your amplifier, which is usually a BJT or MOSFET. When you operate a BJT in active forward region, the current at the collector is (1+beta)* the base current.

    I beg to differ.

    β is current gain parameter normally applied to BJT's.

    More importantly ...

    the collector current is β*Ib

    and

    the emitter current is (1+β)*Ib

    Sorry. I am confused collector with emitter.

    Wow, did your parents really name you 'needs'? :)
