The transformer that feeds your house is a center tapped transformer. Primary 7200, Secondary 240. The 240 volt secondary is center tapped to give you 120 volts on either side of the tap. Hence house voltage is 120 / 240 volts.

Why are center tapped transformers used in North America?
Center tapped transformers are used in North America to be able to use two voltages from the transformers secondary. It is known as a three wire system. Appliances circuits that utilize 240 volts and appliances that use 120 volts can be supplied from one transformer. The transformers secondary is center tapped and grounded. This allows the 240 volt winding L1 - L2 to produce 120 volts from one leg of the winding to ground L1 - N and the second half of the winding 120 volts from N - L2. <<>> Center tapped transformers are used anywhere world wide where ever they were designed to be used. There is nothing particular to a center tapped transformer that makes it more or less suitable for use in North America.
Can you put transformers in series to double your voltage?
You can if done carefully. The neutral of one transformer must be set up to be at the positive voltage of the other transformer. This might require an intermediate step transformer that is center tapped (so three instead of 2 transformers).
Why cant you implement centre tapped full wave rectifier without centre tapped transformer?
The center tapped full wave rectifier depends on two similar windings, each 180 degrees out of phase with respect to each other. You are only going to get that with a center tapped winding. Without the center tap, you need four diodes.
What is a ring distribution system?
This is a system whereby the primaries of distribution transformers form a closed loop. The distributors are tapped from different points of feeder througg distribution transformers... Vspyce naani!
. Which type of full-wave rectifier has the greater output voltage for the same input voltage and transformers turn ratio?
well when you see on basis of output voltage the centre tapped transformers is .
Is 2 diode without center taped can befull wave rectifier?
No. For a full wave rectifier, you need two diodes and a center tapped secondary, or you need four diodes and a non-center tapped secondary.
Are a tapped transformer and a step-down transformer the same?
Transformers can be used in either step-up mode or step down mode, they are just as efficent connected either way. Most large transformers have percentage "taps" to allow voltage corrections up or down by about 15%.
What shape is the building of the military center in transformers?
diamond
Center tap transformers?
Yes....what about them? They are common items.
What is the difference between 208voltc and 240volts?
32 volts of course. But the real difference is the way the power company has "tapped" their supply step down transformers.
What is the difference between an ordinary transformer and a center-tapped transformer?
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
Which types of transformers used in industries?
There are many different types of transformers used in industry. They include polyphase, capacitor voltage, and resonant transformers.
