How is zener diode different from a conventional diode or ideal diode?
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
Why the dynamic resistance of a zener diode different from its static resistance?
The dynamic resistance of a diode, be it zener or otherwise, will be different from its static resistance because a diode is not a resistor, and resistance is not a function of current flow. It is a diode, and a diode has its own characteristic voltage to current curve, forward and, in the case of a zener, reverse.
What are some practical uses of diodes?
Diodes are largely used for changing AC into DC. A half wave diode bridge will use two diodes for this purpose. A full wave bridge uses four diodes to accomplish this task.See related links below.
How could you measure ripple frequency to determine if a diode were open in a bridge rectifier circuit?
Measuring ripple frequency would determine if a diode were open in a bridge rectifier circuit because the ripple frequency is normally twice the input frequency in a functioning full wave bridge rectifier. If one diode were open, the ripple frequency would only be the input frequency. Note: This is true for single phase or bi-phase operation. Three phase operation is more complex, but still doable - You would expect three times input frequency in normal state, and two times (asymmetric) with one open diode.
Will a zener diode work the same as a germanium diode?
No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages. An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.
Why balanced modulator is called balanced modulator?
the output from a balanced modulator consists of modulating freq also. this can be eliminated in a diode modulator by adding two more diodes, making a diode ring. therefore called ring modulator

What is a diode modulator?
A diode modulator is a type of AM modulator constructed using diodes. One type of diode modulator is the ring modulator shown in the image.
What are the advantage and disadvantages of the monolithic modulator in comparison with diode modulator?
hello
Is crystal oscillator used in Varactor diode modulator?
YES
In a diode modulator the negative half of the am wave is supplied by the?
tuned circuit
Where is a diode used?
A diode is used as a rectifier, clipper and to get square wave form. The combination of diode (bridge) is used for full wave rectification. It also used as a voltage controlar. Different types of diodes have different uses in different appliences.
Does the current rating of a diode change when it is used in a bridge rectifier EG A bridge made up from four 10 amp diodes would it have a different total current rating. DD?
A : A diode is an dumb animal he does not care how it is used all it cares is that its limitations are not exceeded
What are merits and demerits of bridge rectifier?
Merits a diode bridge rectifier is simple to build
Purpose of bridge diode in a power supply?
Bridge diodes are generally used in a bridge rectifier to convert AC into DC.
How do you test a diode bridge?
How to test a diode bridge ? Diode bridge is a device is used to convert an AC signals (say AC voltage) to DC output (say DC voltage). So, to test it, you can apply a AC voltage v = Vm Sin (wt) at its 2 inputs and measure DC output voltage Vdc.
What is bridge rectifire?
A four diode circuit to change ac to dc
