What is the difference between rectifier diode and zener diode?
A: They are both diodes. The difference lies in the application. A rectifier is used to rectify AC current into pulsating current. The zener diode is used to regulate a voltage source to the zener voltage when connected in the reverse direction. ************************************************************** If you look at the characteristic curves of a rectifier diode and a zener diode, you will see that they are similar, but the reverse curve of the zener has a much sharper bend at what is called the "knee". It is at this point on the zener's curve at which it operates.
How does zener diode work?
The essential guideline behind the working of a zener diode lies in the reason for breakdown for a diode in converse one-sided condition. Typically there are two sorts of breakdown-Zener and Avalanche. 1.) Zener Breakdown This sort of breakdown happens for a converse inclination voltage between 2 to 8V. Indeed, even at this low voltage, the electric field power is sufficiently solid to apply a power on the valence electrons of the molecule such that they are isolated from the cores. This outcomes in development of portable electron gap sets, expanding the stream of current over the gadget. This sort of separate happens regularly for profoundly doped diode with low breakdown voltage and bigger electric field. As temperature builds, the valence electrons acquire vitality to disturb from the covalent bond and less measure of outside voltage is needed. Hence zener breakdown voltage diminishes with temperature. 2.) Torrential slide breakdown: This kind of breakdown happens at the converse inclination voltage over 8V and higher. It happens for delicately doped diode with vast breakdown voltage. As minority charge bearers stream over the gadget, they have a tendency to crash into the electrons in the covalent bond and reason the covalent bond to upset. As voltage expands, the active vitality of the electrons additionally increments and the covalent bonds are all the more effectively upset, creating an increment in electron opening sets. The torrential slide breakdown voltage increments with temperature.
Zener knee current?
Not 100% sure, but I believe it's the reverse current at which a Zener diode enters breakdown. There is also the Zener max current which refers to the current that must not be exceeded if you do not wish to damage the device and also the Zener test current at which the Zener Voltage is measured. The test current usually lies somewhere (roughly halfway) between the knee and max current.
What is the difference between clippers and half-wave rectifiers?
A clipper is a device designed to prevent the output of a circuit from exceeding a predetermined voltage level without distorting the remaining part of the applied waveform.A clipping circuit consists of linear elements like resistors and non-linear elements like junction diodes or transistors but it does not contain energy-storage elements like capacitors. Clipping circuits are used to select for purposes of transmission, that part of a signal wave form which lies above or below a certain reference voltage level.In half wave rectification of a single-phase supply, either the positive or negative half of the AC wave is passed, while the other half is blocked. Because only one half of the input waveform reaches the output, mean voltage is lower. Half-wave rectification requires a single diode in a single-phase supply , or three in a three-phase supply. Rectifiers yield a unidirectional but pulsating direct current; half-wave rectifiers produce far more ripple than full-wave rectifiers, and much more filtering is needed to eliminate harmonics of the AC frequency from the output.Half-wave rectifierThe no-load output DC voltage of an ideal half wave rectifier for a sinusoidal input voltage is:Where:Vdc, Vav - the DC or average output voltage,Vpeak, the peak value of the phase input voltages,Vrms, the root-mean-square value of output voltage.

What is the material poisson ratio of Epdm?
Depends on the hardness of the formulation. Poisson's ratio depends mainly on the bulk modulus and slightly on the Youngs modulus at very low strains for the subject compound. If the Youngs modulus lies between 0.92 and 9.40MN/m², Poisson's ratio lies between 0.49930 and 0.49993.
What mountain range that lies within the US?
the rocky mountains
