What is the difference between single phase transformer and three phase transformer?
A single phase power supply has two "hot" legs or conductors which have a sine wave that are 180 degrees apart. A three phase power supply has three "hot" conductors which have a sine wave that are 120 degrees apart. You can thank Nicoli Tesla, whose birthday is today for the three phase or polyphase power supply and of course all alternating current!
What is the difference between group velocity and phase velocity in a stationary wave on a string?
The velocity of a wave which maintains consatnt phase at all successive positions during propogation is known as wave velocity or phase velocity. The velocity of a group of waves which maintains constant poditions during the propogation is known as group velocity.
What is the effect of phase different in wave propagation?
Phase difference in wave propagation results in interference patterns. When waves with a phase difference interact, they can either reinforce each other (constructive interference) or cancel each other out (destructive interference), affecting the overall amplitude of the resulting wave. This phenomenon is commonly observed in various wave systems, such as light and sound.
What is the phase relation between oscillating electric and oscillating magnetic fields in an electromagnetic wave?
The fields are in time phase and space quadrature.
What is electric phases.?
A quick lesson on three-phase a.c. terminology.The three energised ('hot') conductors that connect the load to the supply are termed 'lines' or 'line conductors'. The fourth wire, if present, is called the 'neutral' or 'neutral conductor'.Anything connected between individual lines, in a three-phase, three-wire, system, are called 'phases'; anything connected between a line and neutral, in a three-phase, four-wire system, are called 'phases'.So the individual windings of a three-phase alternator or three-phase transformer are phases. The three individual impedances that make up a three-phase load are also phases. The wires that connect the supply to the load are lines.Voltages measured between lines, and the currents through lines, are called 'line voltages' and 'line currents', respectively. Voltages measured across individual loads, and the currents through those loads, are called 'phase voltages' and 'phase currents', respectively.(Ignore anyone who calls the conductors that join the supply to the load, 'phases'. This is quite common but completely wrong!)

Why three-phase rectifier is preferred upon single-phase rectifier?
The choice of single or three phase depends on the available supply. But a three-phase full wave rectifier provides 6 pulses of DC per cycle, while a single-phase full-wave rectifier provides only two. That makes the output DC easier to smooth.
What is the frequency of ripple components in the output of capacitor filter?
It depends on whether or not it is a half wave or full wave rectifier. For a single phase 60 Hz rectifier, a half wave rectifier will be 60 Hz while a full wave rectifier will be 120 Hz. A three phase full wave rectifier will be 360 Hz.
What happens when one of three diode is removed from 3 phase full wave rectifier?
A: Then the phase that the diode is remove will not work or Rather get an output
Why three-phase six pulse rectifier is better than three-phase three pulse rectifier?
By this process all errors to be removed and electricity distribution becomes storng. Rectifier always react all abstraction which law given be Ohms.
How do you derive alternating current from car alternator?
The car's alternator is a three phase generating system. Inside the alternator is a three phase full wave diode bridge that changes the AC generated voltage to a DC voltage.
Schemes of Full wave rectifier?
We couldn't agree more.
What does one mean by 3-phase loads?
Electrical circuits are designed in two phase types. Either single phase or three phase. A single phase is one wave of electricity while three phase is three waves that are offset.
What is ripple frequency of 50 Hz 3 phase full ac supply?
A single phase half wave rectifier outputs ripple the same frequency as the input. A single phase full wave rectifier outputs ripple fundamental twice the input frequency (assuming balanced recitfiers). A three phase full wave rectifier outputs ripple fundamental six times the input frequency. So 50 Hz input would yield 300 Hz ripple. See Sources and Related Links for more information.
What is the Difference between half wave and full wave rectifiers?
Half-wave rectification is achieved using a single diode in a one phase supply, or by using three diodes in a three phase supply. In half wave rectification, either the positive or negative half of the AC wave is passed and the other half is blocked. Since only one half of the input waveform reaches the output, it is very inefficient if used for power transfer. A full-wave rectifier converts the whole of the input waveform to one of constant polarity (positive or negative) at its output. Full-wave rectification converts both polarities of the input waveform to DC (direct current), and is more efficient.
What is the condition of ideal amplification?
full spectrum frequency response no change in wave shape or phase
When was Pelamis Wave Energy Converter created?
