Laboratory 1 Ohm`s Law
... The two most common ways to destroy a digital multimeter are: • In current measuring mode, place the meter in parallel with a power supply (that is, touching the two probes to the two terminals of the power supply) as if measuring voltage. The usual result is a blown fuse. • In voltage measuring mod ...

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.
