PN junction diode made of silicon is the value of voltage depends exponentially on the current through the diode.?
current depends exponentially on voltage: diode equation (approx.) Idiode=k (exp (Vdiode/Vth)-1) k=constant (saturation current, something like a femto ampère) Vth=KT/q => 25.8 mV @ T=300 K, Vth is thermal voltage K=Boltzmann's constant T=junction temperature (Kelvin) q=electron charge
How do you find the value of a zener diode?
It is depend on your requirement .suppose you need a voltage regulator of 5V than you need 5V Zener diode.
What is the reverse recovery time of semiconductor diode?
When a diode passes from forward biased to reverse biased it takes a short period of time for the charge carriers in the vicinity of the junction to recombine and create a nonconducting depletion region. During this time period the diode conducts in the reverse direction, this is called the reverse recovery time. Its different for every kind of diode, to get the value for a specific diode consult the datasheet.
What is the current of a circuit if the voltage is 10V with a 1.2K Resistor and a diode?
you should specify: - circuit topology, I assume a series connection. - diode allows current flow? It depends how it's connected - diode forward voltage drop value if diode is in forward conduction, you have VR=10V - VDIODE and, thus, I = VR/R=(10-Vdiode)/1200.

What is value of dynamic resistance oe p-n junction diode?
Rd= Vt*c/I Vt=KT/q, K=Boltzmann constant C= constant 2 for si 1 for Ge I current through the diode
What are the relationship between Diode voltage and temperature?
The equation relating diode voltage and current is: Id = Is*(exp(Vd / n*Vt) - 1) Where: Id = Diode current Is = Saturation current exp() = exponential function (e^) n = Ideality factor Vt = Thermal voltage The relationship between temperature and diode voltage comes from this Vt, the Thermal voltage, which is defined as: Vt = k*T / q Where k = Boltzmann constant (8.617 * 10^−5 eV/K) T = Temperature in Kelvin q = Elemental charge (1.602 * 10^−19 C) Thus, the temperature affects the thermal voltage (an electrostatic voltage across the PN junction), which affects the diode's Id and Vd properties.
What is diode equation?
It is an equation that describes the I-V characteristic of a diode. In other words, how the current depends on the voltage.The Shockley diode equation uses an exponential expression. See the Wikipedia article on "Shockley diode equation" for more details. However, for many practical purposes, it's accurate enough to think of a diode as being "open" in the "forward" direction (no voltage drop), and having a voltage drop of about 0.7 V (in the case of diodes made from silicon) in the "reverse" direction.

How do you find the ac resistance of a diode?
The ac resistance of a diode is found using the equation: (The change in Vd)/(The change in Id) An easier was is to use the Equation: 26mV / Id. This is a general form as the ac resistance of a diode change as the temperature changes.
What is diode reverse current?
the current which has negative value n passes through the diode is called as diode reverse current
What is the incremental resistance obtained from the diode equation?
The incremental resistance of a diode is the inverse of the slope of the V-I curve at the operating point.

What is the value of the breakdown voltage for zener diode?
It depends on the particular diode. They come in all different values.
How do you know if a value a is a solution to an equation?
If this value a satisfy the equation, then a is a solution for that equation. ( or we can say that for the value a the equation is true)
What are the differences between a normal a normal diode and a zener diode?
The zener diode is optimized for reverse breakdown voltage accuracy and stability. This value and its tolerance is specified in more detail than a normal diode.
