What happens to the current in a secondary that has twice as many loops as the primary?
The current in the secondary winding of a transformer is not determined by the current flowing in the primary winding; rather, it is the other way around.The current flowing through the secondary winding of a transformer is determined by the load to which it is connected. The primary current can then be determined from the turns ratio.
What are the three basic parts of transformer?
core - air, iron, ferrite, etc.windings - one or more coils wound around the core.bobbin - insulating structure used to hold the windings. optional, not needed in every type of transformer. in some types of transformer the windings are prewound on the bobbin then the core is inserted into the bobbin.
Why transformer ratio is secondary winding voltage by primary winding voltage but not primary winding voltage by secondary winding voltage?
The transformer primary winding is connected to the alternating current supply. This causes a varying current in the primary winding, which creates a varying magnetic field in the transformer core. Because the primary voltage is alternating, the flux is also alternating - expanding and contracting, and changing polarity in time with the supply. This alternating core flux 'cuts' the secondary winding/s of the transformer, and induces a voltage in the secondary coil/s. As long as there is a magnetic field that is moving, and a conductor for it to move across, it will induce a voltage in the conductor. While the actual induced voltage depends on the amount of flux, the amount of conductor material and the rate of change of the flux, the actual voltage can be calculated from: Vsec = ((Vprim * Nsec) / Nprim) where V = voltage, N = number of turns of wire in the coil, prim = primary and sec = secondary. Transformers don't work on DC - they give a brief pulse out at switch-on and switch-off, because that's the only times the current is changing and the flux is moving. If you have to transform DC, you use a switching circuit that 'chops' the DC into a series of pulses that simulate AC as far as the 'moving flux' requirements of the transformer are concerned.
Every time you ask for how to find your primary and secondary dns the answer is always something about going to your DNS server hows that your primary and secondary DNS if its only one set of numbers?
It means, you do not have secondary DNS server.
Is a encyclopedia a primary or secondary source?
I believe that a encyclopedia is a secondary source, because the person who wrote it most likely didn't witness every single event in it. __--FROM GENIUS--__
What coil will be greater if the primary coil of a transformer has 40 turns and the secondary coil has 60 turns?
The voltage ratio is 2:3. So for every 2 volts in you'll get 3 volts out. Secondary = 1.5 x Primary Voltage.
What is the analogy for Every day is a winding road?
The lyrics of the song Every Day is a Winding Road allude to the idea that life is unpredictable and surprising. A winding road makes it difficult to see what may be ahead.
What are the primary and secondary colors?
Primary ColoursPrimary colours are colours that are the main ones. They are the first colours that make other colours. You can use non primary colours to make other colours but every colour is made from primary colours. These colours below are the primary colours: RedGreenBlueSecondary ColoursSecondary colours are the next step of primary colours. They are made from them. Here's the secondary colours: Cyan (Green+Blue)Yellow (Red+GreenMagenta (Red+Blue)
What is a secondary key in relational databases?
A secondary key is a field that is identified as being suitable for indexing the data such as a surname, It is used to sort the data in a different order to the primary key, A table can have many secondary keys in fact every field could be a secondary key. Hope this helps !

Are there any teaching certification programs?
Every teacher employed in the primary/elementary/secondary schools of this province, is required by law to hold a valid Newfoundland and Labrador teaching certificate. There are four basic teaching certificates which, in general terms, represent increasingly higher levels of approved degree programs and additional years of university study. Teaching certificates are endorsed according to the type of professional study completed: primary/elementary; secondary; or primary/elementary/secondary.
What would happen if the producer was removed from a food web?
First of all, there's not such thing as "primary producer" it's called producer, but if that happens the primary consumer would die so the secondary consumer who is the one who eats the primary, would eat another animal or die.
