... THEORY: A magnetic pick up is a coil placed in magnetic field. Variation in magnetic field induces a voltage pulse in the coil. Amplitude and frequency of induced voltage pulse depends upon rate of change of magnetic flux. Magnetic flux produced by magnet can be altered by bringing any external magn ...

Introduction to Digital Multimeters
... multimeters have very high resistance between their leads. Never try to read resistance or continuity with a multimeter on a circuit that is energized. Current measuring meters ("ammeters") are always connected in a circuit so the electrons have to flow through the meter. When in the current-measuri ...

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.
