When I am going through newsgroups I saw a thread posted by a member about impedance in a transistor.His question was how can we tell that impedence is present in a transistor when only resistors are present?
But when I am going through the topic I found it all the 3 i.e capacitance, resistance, inductance are present.
Capacitance is present whenever 2 conductors are separated by dielectric.But at low frequencies it is negligible. Inductance is present but the lead acts as wire almost.As we use transistors at low frequencies mostly it don't come into picture.But at high frequencies it has a great effect as current bipases through other way without entering into it.
