Question
This quantity in a varactor diode varies with the applied reverse bias voltage, since this quantity varies inversely with depletion region thickness. An analogy between mechanical and electrical systems compares this quantity to the reciprocal of the spring constant. Close proximity of circuit components at different voltages can cause the unwanted “stray” or (*) “parasitic” forms of this quantity. In a simple circuit with two components, resistance times this quantity gives the time constant. Dielectrics are often included in a class of devices in which this quantity equals cross-sectional area times permittivity over distance and arises between two parallel plates. For 10 points, name this quantity measured in farads. ■END■
