Assuming that you are talking about a p-n junction semiconductor diode, then yes. You can do it mechanically, electromechanically, configure a transistor circuit to rectify, use a thermionic triode (a vacuum tube) or a Mercury arc rectifier. Diodes cannot be used at very high voltages, and mercury arc rectifiers are still manufactured for these applications. It is not unknown for mercury arc rectifiers to be found which are older than the electricians working on them! A full answer would depend upon whether you are talking about simple signal level rectification, i.e effectively blocking negative components of an ac waveform, or power rectification, i.e converting ac to dc at high current, high voltage, or both.

Which two tasks can you perform by using a presentation prgram?
control &alt.
What are tools and methods to help humans perform Task?
All tools help humans (and rarely, animals) to perform tasks. So pick a tool, any tool. Then think about how you use it. That's a method of using it. If the task you need to perform is to safely knock down a wasp's nest, the tool you want may be a rock, and your method of using it is to throw it at the wasp's nest.
What activities are involved in the process of computing?
Computing is the act of using a computer. This can be anything from gaming, surfing the web, to banking. There are numerous activities that people perform using the computer.
Does computer perform multiplications and subtraction.?
Yes. In windows its often located in Start > Programs > Accessories > Calculator. They perform this using a math processor built into the CPU (Central Processing Unit). Older computers had a separate math processor called a Math-CoProcessor
Suppose you want to perform a basic search for documents?
You can either create a dedicated search centre site using the search template or use the search box available in all the sites to perform searches. Ensure that search has been configured in central administration and content DB crawl has been done.
What is the advantage of using the bridge rectifier over the two diode form in the full wave rectification?
the ease of filtering their outpot voltages
Can you perform rectification without using a semicondutor device?
Yes; solid state rectifiers were made using values (also called vacuum tubes). ************************************************************* A solid state device is a semiconductor device. A valve (vacuum tube) is a thermionic device, so yes, rectification can be achieved with a thermionic rectifier.
How diode convert pure ac to pure dc?
You can't convert ac to pure dc with diode only. The easiest way to convert ac to dc by with diode is by using rectification, it consist of at least 2 diodes (half wave rectifier) and (capacitor is to "smoother" the wave).
What are special purpose diodes?
Special diode does special function. Diodes are originally used to rectify ac current into dc current . Other versions of diodes are constructed in a similar way using the same principles but their function is not rectification such as light emmision diode
What is the function of capacitor in rectifier?
is a device that smoothen your half-wave rectification into a full-wave rectification after using a 4 diode and 1 resistor , after adding a capacitor , there will be a almost steady output , it charges the capacitor when is forward biased which is the first half wave , and discharge when is reverse biased to stablelize the wave into a almost same potential difference compare to a.c
What are the different between uncontrolled and controlled rectifier half wave?
uncontrolled wave rectification is achieved using a single diode in a one phase supply, or by using three diodes in a three phase supply. In uncontrolled wave rectification, either the positive or negative half of the AC wave is passed or the other half is blocked. Since only one half of the input waveform reaches the output, it is very incompetent if used for power transfer. A controlled wave rectifier uses a thyristor instead of a diode, therefore the firing angle can be adjusted with a gate pulse.
What is the difference between a half wave rectifier and a negative clipper?
As far as general principles apply, they both perform the same function: using a diode.
Can you produce electricity even without magnetism?
yes we can produce electricity without magnetism by using semiconductor for example photo diode is used in solar cells.
How do you perform a factory reset on a computer without using the keyboard?
you don't
What is a power diode?
A Power Diode is used when a large current is involved which needs a larger junction to dissipate the heat generated. An advantage of using the Power Diode is it is able to withstand high voltage without being damaged. A disadvantage about the Power Diode is that being a large junction it is unable to stand high frequency applications.
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.
What happen to a bridge diode rectifier if one of the diodes is defected?
you have to have direct current to charge any battery alternating current is constantly changing polarity in pulses back and forth so when it sends electrons into a battery to charge it it alternates polarity and removes the charge from the battery direct current never changes polarity it is a constant supply of power If one diode is removed or the defect in one of the diodes is a break in the circuit as apposed to the default allowing power to flow either way then you would get half wave rectification which is direct current in pulses it is not constant it would charge your battery but is inefficient use of your alternator as you would only be getting half the normal charge If the faulty diode allows current to flow in both directions then you would get half wave rectification in one direction and a short circuit in the opposite pulse.I believe this would damage the alternator windings but i have no proof of this half wave rectification has been used in the past but is not common as diodes are so cheap nowadays and because the alternator using half wave rectification was very inefficient
