A diode or rectifier converts AC to DC.

Ultrasonics are sound waves with frequencies above 20khz. GALTON WHISTLE First they were produced by Galton.He called his Instrument the galton whistle.It consisted of a brass tube 2 mm in diameter and it was operated by blowing in a jet of high pressure gas.it consisted of a piston.on moving it the resonant cavity's length varied,on varying the length the resonant frequency too varied.Thus the resonant frequency depends on the length of the tube/pipe.But this could produce only up to 30khz. MAGNETOSTRICTION METHOD the main principle for this method is when a ferromagnetic rod made of material like iron or nickel is subjected to alternating magnetic field applied parallel to the rod,there will be a small elongation or contraction in its length.this change in length is proportional to the intensity of the magnetic field and nature of the ferromagnetic material. so the length of the rod changes for each half cycle of the alternating current which means the frequency will be twice the frequency of alternating current.. when the natural frequency of the rod matches with the frequency of the alternating current resonance occurs and amplitude will be maximum and ultrasonic waves are produced.In this method frequencies up-to 300KHZ can be produced. PIEZOELECTRIC OSCILLATOR The main principle of this is the inverse piezoelectric effect..according to the piezoelectric effect,when one pair of opposite faces of a crystal like quartz is subjected to pressure the other pair of opposite faces will develop electric charges and if the pressure is replaced by tension then the charges will be reversed..the inverse of this effect is that if the pair of opposite faces are subjected to alternating voltages then the other pair of opposite faces varies in its dimensions,i.e. it expands or contracts periodically thus generating elastic waves.When the natural frequency of the crystal matches with the frequency of the alternating current,resonance occurs and ultrasonic waves are produced.In this method frequencies upto 500MHZ can be produced.
A "serial to parallel" converter converts a serial data connection to a parallel data connection. For example, in computer storage, there are controller chipsets that convert SATA (Serial ATA) to PATA (Parallel ATA, also called IDE or EIDE).
Yes, this model will need a converter box to function after the digital conversion. I have the same television and called SONY to find out. The model has an analog tuner, therfore it requires a digital to analog converter box. This model is capable of high definition video quality because it has a picture resolution of 1080i. I am buying the Samsung DTB-H260F Digital Receiver for a converter box because it will provide the television with a high definition analog signal through the component video outputs. If you buy a lesser converter box it will only provide a 420i signal to the television even if an over the air high definition signal is available.
It is made out of small particals, smaller than atoms called electrons.
Alternating Current can be converted to Direct Current by using a DC Converter which contain a Bridge Circuit , a Capacitor and if needed a Transformer.CommentA 'DC converter' is normally called a rectifier.

flow of charge
It's alternating current
It's called an inverter.
There are only two kinds of electricity, direct current and alternating current. All power plants now produce alternating current
Direct current is a constant, steady state current, such as obtained from a battery. Alternating current is constantly switching polarity, usually in a sinusoidal waveform, such as obtained from an alternator, a form of generator that does not have a commutator.Direct Current and Alternating Current:The first and simpler type of electricity is called direct current, abbreviated "DC". This is the type of electricity that is produced by batteries, static, and lightning. A voltage is created, and possibly stored, until a circuit is completed. When it is, the current flows directly, in one direction. In the circuit, the current flows at a specific, constant voltage (this is oversimplified somewhat but good enough for our needs.)The other type of electricity is called alternating current, or "AC". This is the electricity that you get from your house's wall and that you use to power most of your electrical appliances. Alternating current is harder to explain than direct current. The electricity is not provided as a single, constant voltage, but rather as a sinusoidal (sine) wave that over time starts at zero, increases to a maximum value, then decreases to a minimum value, and repeats.
The electrons flows from negative to positive and then positive to negative.The pole of the flow of electron changes at a time interval.This is called alternating current (AC).
This is known as a direct current or DC. The two major types of currents are AC (alternating current) and DC (direct current). In AC the charges move back and forth, but in DC the charges flow in JUST ONE DIRECTION. Due to this characteristic it will not reverse direction like AC can.
In one direction - or constant - is called direct current. The other sort is called alternating current.
It's called Alternating Current (AC) as opposed to Direct Current (DC/batteries).
There are two types of electric current, DC or direct current and AC or alternating current. The power delivery to homes in most places in the world is AC or alternating current. This is where the electrons are pushed one way then back the other way with usually 100 or 120 changes in direction per second. This produces 50 or 60 forward/back cycles every second called 50Hz or 60Hz.
