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.
What else can I help you with?
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
What is the formula for total current in a series 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.
What is the relationship between the voltage output at the interface and the voltage across the series and parallel 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.
What is another name for a series -parallel circuit?
series other name current series and parallel is voltage
An example series circuit might be what?
A voltage or current source in series with a circuit breaker or fuse in series with a switch in series with a light bulb.
What are the 2 rules for the voltage and current in a series circuit?
In a series circuit, the current remains constant throughout the circuit. The voltage across each component in a series circuit adds up to the total voltage of the circuit.
How do you convert voltage series into current series?
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?
What are three characteristics of a series current?
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.
If voltage is increased in a circuit what happens to current series and parallel respectively?
In this case current flows from a high voltage to a lower voltage in a circuit.
What is the formula for total current in a series 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.
What is the relationship between the voltage output at the interface and the voltage across the series and parallel 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.
State two rules for the voltage and current in a series circuit?
Kirchoff's voltage law and Kirchoff's current law
How is the current affected in a series circuit?
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 series circuit why current drop beceause according to kichroff law cuurent remain same in series circuit?
In a series circuit current does stay the same thoughout the circuit, voltage drops in the series circuit.
What is another name for a series -parallel circuit?
series other name current series and parallel is voltage
What is the difference between parelllel and series circuit?
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.
How does a series circuit increase voltage?
In a series circuit, the voltage increases as the electrical current flows through each component in the circuit. This is because the voltage across each component adds up, resulting in a higher total voltage at the end of the circuit.
