The voltage and current characteristics of a zener diode in the forward bias condition (anode more positive than cathode) are similar to an ordinary diode.
Below the cutoff voltage, the current is near zero, excepting for leakage current. Starting at the turnon voltage, the diode starts to conduct. As voltage increases, current increases. At this point, increases in current result in very small increases in voltage. Above the breakdown current, the diode tends to self-destruct. The cutoff voltage for a silicon diode typically ranges from 0.6V to 0.7V, and the beginning of the flat region ranges from 0.7V to 1.4V, depending on the current rating of the diode. The cutoff characteristic is also highly dependent on temperature.
It is important to understand that, while the current to voltage curve is relatively flat between the cutoff and breakdown points, it is not completely flat. This is normal diode behavior.
In the reverse bias condition (anode more negative than cathode), the zener diode behaves very much like its forward bias condition, except that the cutoff voltage and flat region range are higher and, sometimes, flatter. This is what a zener is used for - it makes a good voltage regulator.
A: A zener is a diode that has the property when reversed bias is applied to breakdown at a particular voltage and remain in that mode until the input voltage is reduced below the reverse breakdown. For that reason it is used for regulation for control the voltage across a load
In a series circuit current will be same, but voltage will be different across various elements.
In this case current flows from a high voltage to a lower voltage in a circuit.
Current = (Voltage across the circuit) divided by (Total resistance of the circuit). The current is the same at every point in the series circuit.
Ohm's law states that the current in a circuit is inversely proportional to the circuit resistance. There is a single path for current in a series circuit. The amount of current is determined by the total resistance of the circuit and the applied voltage.
series other name current series and parallel is voltage
A voltage or current source in series with a circuit breaker or fuse in series with a switch in series with a light bulb.
well current in a series circuit wont change so a voltage series is also a current series probablyAnswerYour question makes little sense. Applying a voltage across a series circuit results in current through that circuit, so what exactly are you asking?
There is one and only one current path through it.The current at every point in the circuit is equal.The sum of the voltage drops across each element in the circuit is equal to the supply voltage.

Kirchoff's voltage law and Kirchoff's current law
A: In series circuit the current remains the same no matter how many components are in series. just the voltage will change to reflect different voltage drops for each.
In a series circuit current does stay the same thoughout the circuit, voltage drops in the series circuit.
series other name current series and parallel is voltage
A parallel circuit has the same voltage but different current in each leg and series circuit has the same current but different voltage on each components unless the same value.
No. The current in a series circuit is the same everywhere. The voltage across a parallel circuit is the same.
If the voltage between the ends of a series circuit changes, the current in thecircuit definitely does not remain constant. The current does change by the samefactor as the voltage.The current at every point in the series circuit is the same current.
