How does 120Volts single phase convert to 220Volts 3 phase when the 3 phase voltage should be 208Volts ie 120V x sq route of 3 equals 208V?

If you get 220 volts instead of 208 volts it means that the transformer supplying the circuit is wired in Delta with one of the legs center-tapped to ground.

What type of device is used to convert the high voltage on a feeder line to a lower voltage that can be used on the plant floor?
To convert the high voltage on a feeder line to a lower voltage that can be used on the plant floor you use a transformer.
A 220volts series motor takes 15amperes and runs at 700rpm the armature resistance of the series winding is 0.8 ohms at what speed will it run if resistance is connected in series with supply voltage?
It will run slower because the resistance in series with the motor will take some of the voltage and thereby reduce the current to the armature windings (less magnetic field).
What is the output of the control transformer?
Depends on what the voltage is being stepped down in that particular control transformer. Control transformers usually step down a voltage of 480/208v to 120V. The 120Volts can now be used in safer manner to "control" start/stop buttons, and other components that are only built to run on 120V
How will you convert a open current circuit to a open voltage circuit?
The first thing you need to know is the internal resistance of the current source, the voltage source will have the same internal resistance. Then compute the open circuit voltage of the current source, this will be the voltage of the voltage source. You are now done.
What is the formula to convert voltage levels to decibels?
Here you find the formula to convert voltage levels to decibels. Scroll down to related links and look at "How to calculate dB?"
I bought ps2 in the US can i plug it to a 220volts in the philippines?
No the US voltage is much lower and it will need a transformer
What is the current in an ac circuit with 120volts and a 60watt light bulb?
Power = Current * Voltage Current = Power / Voltage Current = 60 W / 120 V Curretn = 0.5 A
Can you interconnect 110voltage and 220volts?
Not in any way that's simple enough to be explained here. mains voltage can easily kill and destroy property.
What transformer is needed to convert 220volts to 110 volts?
Yes, transformers which operate on 110 - 120 Volts exist. This question is probably incomplete as it only mentions one voltage: it could be for the primary or the secondary or for a single-winding auto-transformer. The missing information cannot be guessed...
What kind of adapter to you need in the UAE?
voltage is 220volts, they use the three prong English-type plug socket although adaptors are readily available
How do you convert 23 voltage DC to 230 Voltage AC?
How do you convert 23 voltage DC to 230 Voltage AC?
How is the voltage for homes shipped to a home?
Voltage isn't "shipped", really. Generator terminal voltage is typically in the range of 10-30kV; they are connected to the bulk electric system by step up transformers that convert this 10-30kV into voltage in excess of 100kV for power transmission. Near your home, this voltage is again stepped down to sub transmission voltage levels, then distribution voltage levels. The small power lines near your home are probably distribution level power lines (often 2 - 20kV); these will have a center tapped step down transformer to connect your home, at 120volts, to the grid.
Formula for converting US voltage to India voltage?
There is no formula to convert voltage. Voltage is universal.
Why is rectification needed?
To convert AC voltage to DC voltage.
Using a power tool that is 120volts with a 115volt transformer?
If you are in north America, 120 is a 'nominal voltage' printed on many power tools. In fact they will almost all work on voltage between 105 and 130, as long as using 60 hz.
When do you need to convert the voltage for appliances?
You need to convert the voltage if your appliance requires less voltage than you power supply. example: appliances is 110V and power supply is 220V.
Does centre tap transformer convert ac voltage to ac voltage?
Yes. Transformers convert power by stepping up or down voltage. It doesn't matter what tap configuration they have.
