    Hey can anyone tell me what would be voltage across the diode when it is used in the full wave rectifier??
    i mean will it be Imax*Rl / 2 ??

    The diode voltage includes two general "regions" - either when the diode is forward biased and conducting OR when the diode is non-conducting and reverse biased.

    Generally for a Si rectifier we assume the forward conduction voltage is typically 0.7V. The peak inverse voltage depends on the AC supply voltage and rectifier type / configuration.

    You can model the diode behaviour using the diode equation if you require a better estimate (say in the forward biased conduction case) - but that requires some further knowledge of the particular diode's physical parameters.

    Well. more over can anyone explain me the static output and input characteristic of transistor in CB, CE and CC mode?? i cant quite understand why the curves are the way they are??
    Also something about saturation and cut off region... [​IMG][​IMG]
