... The circuit above is used to investigate the charge and discharge of a capacitor. The supply has negligible internal resistance. The capacitor is initially uncharged. When the switch is moved to position 1, electrons move from the negative terminal of the supply to the lower plate of the capacitor. ...

... less. This is the enabled mode, hence the name of the pin. When the EN pin is left unconnected or is forced to at least 2V above the negative supply voltage, the amplifier is in shutdown mode and draws only 150µA of standby current. To adjust or program the supply current and speed of the LT1815, co ...

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.
