... In any working circuit the current flows from the high potential (+) to the low potential (-). The potential is designated as the voltage, V. A successful circuit will allow you to follow the path of current through the devices. In reality electrons travel from low potential to high (which is from h ...

... If I2 is zero that means that port 2 should be an open circuit, so no current can flow into port 2. So V1 divided by I1, when we look at the circuit, is the equivalent of the impedance; or we can call it the equivalent resistance across a and b. No current flows through the 3.3-kilohm resistor. It i ...

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.
