What is difference between transformer and center taped transformer?

Not a big difference, an ordinary transformer only have one voltage out for instance 12 Volt, where a center tap can supply two X 6V with the center tap as 0 volt and 12V it is normally called a 6-0-6 or 9-0-9 an advantage of the center tap is that you only need two diodes to get full wave rectifying where with a ordinary you will need a full bridge to get full wave rectifying

∙ 12y agoThe construction of a centre-tap transformer is the same as any other mutual transformer: a primary and a secondary winding, wound around a silicon-steel core. Typically, a centre-tap transformer is a distribution transformer, used to step down the high-voltage distribution voltage, to a low-voltage suitable for supplying one or more residences.
The secondary (low voltage), 240-V, winding has three terminals: two connected to opposite ends of the winding, and a third connected to the centre of the winding. The centre-tap terminal is earthed (grounded) and provides the neutral which is then at approximately earth potential (by general agreement, zero volts), while the outer terminals are at 120 V with respect to the neutral.
So a centre-tap transformer is used to provide the standard 3-wire 240/120-V low-voltage residential supply that is standard in North America.

Why a full wave rectifier is preferred over a half wave rectifier?
The a.c. component, or ripple, produced by the 4-diode (full wave) bridge rectifier is the same as that produced by the 2-diode full wave rectifier. The bridge is connected across the secondary winding of a transformer. The 2 diodes of the other type of full wave rectifier are each connected to one end of a winding, but that winding requires a center tap. For any desired value of d.c. after rectification, the a.c. voltage of the 2-diode rectifier winding has to be twice that of the winding required for the bridge.

How does electricity get to a plug?
The electricity is produced by large generators in a power plant.Transformers in the power plant yard step up the voltage to more than half a million volts used by the power transmission lines.Power transmission lines carry the electricity over long distances between the power plants and cities.Transformers in a switching yard step the voltage down to 1000 to 5000 volts used by power distribution lines.Power distribution lines carry the electricity short distances between the switching yard and the customer locations.Service drop transformers on the pole or underground step the voltage down to the voltage needed by the customer (e.g. 220 volts center taped for household, 240 volt 3 phase for commercial, 480 volt 3 phase for industrial).Service drop lines carry the electricity from the service drop transformer to the customer's electric meter.Internal main wiring carries the electricity from the electric meter to the breaker box.Wires from the breakers in the breaker box to outlets carry the electricity to the outlet sockets.When you put a plug in an outlet socket, the plug gets electricity.
First computer bug in 1945?
Operators looking for the cause of a malfunction in Harvard University's Mark II Aiken Relay Calculator on September 9, 1945 discovered a moth trapped in its innards and Scotch-taped the unfortunate creature to the computer log over a caption reading, 'First actual case of bug being found.'
How Alfa Laval oil separator works?
It works due to the oil having a lower specific gravity then water, in other words oil is lighter then water, if you mix oil and water in a jar and leave it over a period of time the mix will separate and the oil will float to the top because it is lighter, this is caused by gravity. in a separator this process is speed up by filling the bowl full of oil/water/impurities of different specific gravities and spinning it at high speed this results in a large centrifugal force acting on the fluid several times greater the natural gravity of earth, this means the fluid separates faster with the heavy impurities thrown to the outer edge of the bowl with the water next then the oil. The oil then leaves the center of the bowl cleaner then it was when it entered. Due to this separation you have a oil water interface the water can also get taped off here if you have a large water content in the oil. the impurities will just build up unless the bowl is self cleaning meaning in a set period of time it goes through a cleaning cycle that makes a opening at the extremities of the bowl allowing the impurities to exit and collect in a sludge tank. I hope this helps

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.

What is the difference between direct and indirect measurement in surveying?
Direct Measurement: Apply the instrument directly to the unknown quantity. E.g. Taped distance, direction measured with a theodolite Indirect Measurement: Determined from its relationship to direct measurements. E.g. height difference determination in trigonometric leveling

What would be your reaction to having your boss videotape you on the job?
This actually happens at most work places: if the business has any type of surveillance system, the employees are being taped. If you're doing your job, it shouldn't make any difference to you whether you are being taped or not.
