Why are stripes of iron plates joined instead of using a single block of iron core in a transformer?

To reduce heat generated and eddy current losses in transformer's core during operation.

What is through fault?
A fault occurs by 2 plates sliding along each other and then breaking.
What are the factor affecting capacitances of capacitance?
The area of the sheets, the distance between them, and the material between them.
What are paper plates made of?
Paper plates are made of byproducts of the paper making process. Cellulose, oil, resin and various wood chemicals. The designation paper plates generally refers to all disposable plates. 57% of so called "paper plates" are made of polystyrene, which although not biodegradeable us much less energy to manufacture.
What are electrolyte plates in a grounding system?
Electrolyte plates in a grounding system are electrically grounded metal plates on which a person stands to discharge static electricity picked up by his body. This is called grounding.
How do you use transformers on DC supply?
In order to pass DC current through a transformer you would need some basic knowledge of what a transformer actually is. A transformer is simply put a coil of copper wire around metal plates of iron. When you put current onto the coil, the metal plates will build up a magnetic field. During the build up of this magnetic field, the current will be 'low' When the magnetic field is maximized, the coil will work as a shortcut on a DC power source. In order to use a transformer, ie transform voltage up or down, we need a fluctuating magnetic field. This can not be done without electronics of some variety, and the resulting voltage will be AC, not DC. The easiest way to use a transformer with a DC power source is to make a circuit that electronically change polarization of voltage back and forth. Depending on transformer, this can be as low as 50 times per second (EU standard 50 Hz AC 220 Volt, US standard 60 Hz AC 115 Volt) or higher like 100.000 times per second (100 Khz) as is in many high speed switch power supplies. It all depends on the transformer you use and what you want to use it for. If say you want to make a power source for an electric drill and you want to use a car battery as the source, then I would forget it. An electric drill need a lot of juice and in order to do so via a transformer, this transformer would need to be very very large. Every ampere of 12 Volt would only give you approx 0.07 Ampere of 115 Volt. A drill easily drain 800 to 1000 Watts. Approx 8 Ampere at 115 Volt. Following this, an ideal transformer with hardly any loss would eat away 100 Ampere every 8 ampere on output 115 Vac. With the loss factor (some of the transformed voltage will be given away as heat) and you would probably need approx 110 Ampere 12 Volt in order to generate 8 Ampere 115 Vac. A normal 60-65 Ampere car battery would then last a mere half hour fully charged. Another problem is that most batteries are not designed for such a load over any prolonged time (more than 30-60 seconds). Systems have been and are buildt that can withstand such a drain but they consist of many batteries connected in paralell in order to even the drain between all batteries.
What is the core made from in a step up transformer?
Laminated steel plates.
What are the basic construction of a single phase transformer?
two coils and a metal plates
What is a mixed up plate?
It is all the plates joined up , its a pattern.
What is cazan - a mixed up plate?
It is all the plates joined up , its a pattern.
What can tectonic plates also be called instead of tectonic plates?
Tectonic plates are also "Continental Crust" and "Oceanic Crust". Also lithospheric plates.
What might the consequuence be of pouring the plates 2 mm deep instead of 4 mm?
You would break half as many plates by pouring only 2mm worth of plates onto the floor instead of pouring 4mm worth of plates on the floor.
What is through fault?
A fault occurs by 2 plates sliding along each other and then breaking.
The theory that plates were once joined together and gradually moved apart was called?
The theory of plate tectonics

Well The Euroasian plate and the African late i think
What do some whales have instead of teeth?

What do sacral vertebrae and bony plates of the skull and the epiphyseal plate have in common?
a. joined by fibrous tissue b. joined by hyaline cartilage c. ossify as you get older d. they are all examples of sutures
How do you frame with metal studs?
They screw into the top and bottom plates instead of nailing in.
