... 1. Pick a reference node, “i.e., “ground”, to which all other node voltages are referenced. The reference node is usually at the bottom of a circuit. Reference node voltage is zero by definition. 2. Identify major nodes and supernodes, and wrap each in an imaginary surface for KCL equations so that ...

... is needed is that it drops below 0V to reverse-bias the thyristor. The load usually has a low resistance, and so when the thyristor switches off, a large current flows through the load and onto the left-hand plate of the capacitor. The voltage at P rises quickly to +12V. Similarly, when S2 is releas ...

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.
