Unformatted text preview: a certain range of forward bias, there is a negative resistance region, meaning increasing voltage resulting in lower current. Such a device with negative resistance can be used in oscillators. 7 The capacitance C is how much charge can be stored when a voltage is applied. C’ here means capacitance per unit area. It is the ratio of the change in charge per unit area (dQ’) in reverse bias to the change of applied v...
