Why is the wire in the primary coil is made thick than of secondary coil in step up transformer?
i have no idea but maybe this is a possibility voltage is inversely proportional to current the voltage in the primary coil is lower than in the secondary therefore the current in the primary coil is higher than in the secondary coil in order to reduce energy lost in the primary coil, the resistance is lowered by increasing the cross-section area of the coil as R is inversely proportion to area So maybe it is thicker to reduce energy lost in the form of heat, thus making the transformer more efficient
How does the power transformers works?
Power transformers convert an alternating electric current into magnetism in the primary circuit. This magnetic flux flows around the core in the form of a fluctuating magnetic field. This flux is transformed back into an electric current in the secondary circuit . The primary circuit consists of a coil of wire, having a known number of turns, wound around a laminated soft iron core. The secondary circuit is also wound around the magnetic core but is electrically isolated from the primary.The linkage between coils is purely magnetic. The number of coils on the secondary dictates whether the transformer steps up the voltage on the primary,or steps it down. It is a simple correlation of turns.ie 100 coils on primary,50 on secondary halves the voltage and doubles the available current on the secondary. They are the most efficient electrical machines ever invented.
What are stepdown transformers used for?
A step-down transformer accepts a given voltage on the primary winding (coil), and outputs a lower voltage on its secondary winding. A good example is a doorbell transformer you might buy for your home. It uses 120 volts from the house electrical system and steps it down to a safer 18 volts used to ring the doorbell. The voltage produced is a function of the 'turns-ratio' of the transformer. For example, if the transformer has 500 turns of wire in the primary, and 125 turns of wire in the secondary, we would say it has a turns ratio of 4:1 (pronounced "four-to-one"). If we feed 120 volts into the primary, the secondary would produce 30 volts. 120:30 = 4:1
Who is the biggest of all transformer?
it would still be sideswipe whos the fastest in transformers 3, and how did you think that dino (mirage) is the fastest in transformers 3? is it becuz of the time when he grappled hatchet (fastest decepticon on foot) hatchet pulled him and dino look like he skated? bruh, it would still be sideswipe, he was known to be the speed of the autobots, he was an assasin dude.
What actors and actresses appeared in This Mortal Coil - 2013?

What is meant by a primary coil and a secondary coil?
In a transformer, the primary coil is the coil that has voltage applied to it. The secondary coil is the coil that we take voltage from. Transformers are used to step up voltage, step down voltage, or simply to isolate circuits.
What do you need for a Tesla coil?
Transformers Primary Coils Capacitors Spark Gaps Secondary Coils Toploads
What are the two coils in a transformer?
primary and secondary coilsAnswerPrimary and secondary windings.
Why is the number of turns in primary coil more than that of the secondary coil?
The number of turns or windings of a transformer can vary. There can be more in the primary, or more in the secondary, or there can be an equal number in a transformer that is simply used for isolation (an isoformer). More turns in the primary than secondary will create a step down transformer. More turns in the secondary are found in a step up transformer. The transformers on power poles have more turns in the primary to step the line voltage down for delivery to residential customers.
How does a power mat for an Android device work?
The primary coil is in the power mat while the secondary coil is in the Android device. Power goes from the primary coil to the secondary coil, which allows the phone to charge.
If the voltage in a transformer is twelve volts and the primary coil has ten turns and the secondary coil has twenty what is the voltage across the secondary coil?
I assume the primary has 12 volts applied. The voltage ratio from primary / secondary is equivalent to the turns ratio = 10/20, so the primary voltage is 1/2 of the secondary voltage. The secondary voltage is 24.
How can a change in voltage of a transformers primary coil create a change in the secondary coils voltage without the coils touching?
The more coils you have on one side will increase the magnetic force
What is the maximum voltage on the secondary side of the transformer?
Transformers come in very many varieties and voltages. Transformers have ratings regarding the electrical power that they are connected to. The most important ratings are voltage, power and current. In general the insulation level and number of windings in the secondary and primary determine the maximum rated voltage, and the size of the magnetic wire that makes up the windings, and mass of the iron core, determines the rated power and rated current. It is the insulation level therefore, that determines the maximum, safe voltage that can occur on both the secondary side and the primary side. The turns ratio between the primary and secondary coils of the transformer determines the secondary voltage with respect to the primary voltage. If the primary coil has 1000 turns, and the secondary coil has 100 turns, the transformer turns ratio (usually designated by the letter "a") is 100 / 1000 = 0.1. If a = 0.1, then if 1000 volts are applied across the primary coil, ideally, 100 volts will be measured across the secondary. Transformers have been manufactured with secondary voltage ratings in the range of millivolts, to 1,000,000 volts.
How do transformers work since the two coils aren't connected to each other?
The AC - and it must be AC - in the primary coil generates an alternating magnetic field around the coil; this alternating magnetic field induces a current in the secondary.
Difference of step up and step down in terms of no of loops in the secondary coil?
If the primary coil has ten loops and the secondary coil has five loops then the secondary coil works as a 50% step down
