... In a feedback /regenerative circuit, there will also be unpredictable couplings via stray capacitance. The real series capacitor and the diodes self-capacitance form an ac voltage divider, so SOME ripple WILL get through. And there may be modulation effects due to power supply loading. Whether you c ...

... Substituting IB = 0.0001 mA gives Y = −4U + 0.004 so there is an output error of 4 mV. (b) This time, the current IB flows through the 8 kΩ resistor so V+ = −8IB . As before, we assume Q−Y that Q = V+ also. Then KCL @ Q gives Q−U 10 + IB + 40 = 0 from which −4U + 40IB − Y + 5Q = 0. Substituting Q = ...

Electrical ballast



An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
