You have a 2-to-1 step-up transformer. The voltage across the secondary
winding is 200 volts.
The power in the secondary winding is the power required by whatever
200-volt device you connect across that winding.
The power drawn by the primary winding from the 100-volt AC supply is
somewhat more than the power delivered to the device by the secondary,
since some power is lost in the transformer wire and core. That's why the
transformer hums and gets warm.

How do you calculate radius?
Radius is calculated by dividing diameter by two. Measure the distance across the circle then divide it in half for example: You measure the distance across the circle (the diameter) = 6, then 6 divided in half, the radius is 3.
How do surveyors use trigonometry?
If you know two sides of a triangle, trig lets you find the third. So if you want to know the distance across a lake, measure two lines along the side of the lake such that they form a triangle with the line across the lake, and you can find the distance across. You can also find one side if you know one side and the angles at either end. This can be used to find the heights of objects - you know the angle it makes to the ground, how far you are from it, and what angle you have to look at to see the top.
What is the definition of the word transverse?
The definition of the word "transverse" is: situated or lying across; crosswise. Some synonyms for "transverse" are: crosswise, transversal, cross, and thwartwise.
What is the typical width of a tornado funnel?
Tornadoes are around 500 feet (150 m) across on average and stay on the ground for 5 miles (8 km).
Is deny and traverse a synonym?
Are deny and traverse synonyms No. deny means: to say that you did not do something that someone has accused you of doing or to say that something is not true or does not exist. traverse means: to move over or across an area
How voltage is measured in potential transformer?
By connecting a voltmeter across the secondary terminals of the voltage/potential transformer. The transformer acts to reduce the voltage applied to its primary winding, while electrically-isolating the primary (usually high-voltage) circuit from the voltmeter.
Will transformer operate if a battery is used for the input voltage across the primary?
Transformers only work on a.c. This is because it's necessary to have a changing primary current in order to induce a voltage into the secondary winding.If you connect a battery across a transformer, it will not work. Furthermore, if the voltage of the battery matches that of the rated primary voltage, the resulting very large d.c. current is likely to overheat the primary windings and even burn it out.
What type of voltage is passed trough a transformer?
Voltage doesn't 'pass through' anything! Voltage is another word for 'potential difference', and is measured between two points in a circuit. For a transformer to work, it's necessary to apply an a.c. voltage across the transformer's primary terminals.
What is stepup transformer?
A step-up transformer produces a voltage across its secondary winding which is higher than its primary winding. The secondary winding is connected to the load, while the primary winding is connected to the supply.
How do you measure the power input and power output for the step-up transformer?
Power input to a transformer = (voltage across the primary winding) x (current through the primary)Power output = (voltage across the secondary winding) x (current through the secondary)It doesn't matter whether the transformer is used in step-up, step-down or simple isolation.
What is used to increase or decrease the voltage across a power line?
The device that increases or decreases the voltage impressed across a power line is known as a voltage regulator. A voltage regulator is a type of transformer where the primary and secondary turns ratio are fairly close; one (primary or secondary) often has a tap changing ability to add or remove several windings, allowing more dynamic control of voltage.
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.
What is the mutual coupling in single phase transformer?
primary winding flux links with secondary winding produses voltage across the secondary winding
What are step-up and step-down transformers?
A Step Up Transformer is one whose secondary voltage is greater than its primary voltage. This kind of transformer "steps up" the voltage applied to it.The Step Up transformer is designed to increase the voltage from the primary winding to the secondary winding.A Step-Down transformer is one whose secondary voltage is less than its primary voltage. The step down transformer is designed to reduce the voltage from the primary winding to the secondary winding. This kind of transformer "steps down" the voltage applied to it.The basic equation for stepping up or stepping down the voltageNp/Ns is known as the turns ratio.The induced voltage in the secondary winding (Vs) is in proportion to the primary voltage (Vp) and is given by the ratio of the number of turns in the secondary (Ns) to the number of turns in the primary (Np).I to answer basic transformer questions.
What happend if secondry is kept open in Current transformer?
A CT attempts to push a specific ratio of primary current through the secondary. If the secondary burden is a very high resistance (as in an open circuit), the voltage developped across the secondary will build up until it reaches the theoretical limit of the primary voltage. Before it gets to this voltage, it will arc across the air gap in the secondary open (often between two terminal blocks). As an old tech once told me, you only open the secondary of a CT once...the arcs can be fairly spectacular.
Why do you represent leakage flux in a transformer by inductive reactance?
A transformer is often represented by an equivalent circuit, in which the transformer itself is considered to be 'ideal', and its basic losses are then represented as resistance and reactance in series with both the primary and secondary windings for a loaded transformer, or just on the primary side for a transformer on open circuit.The transformer's primary flux comprises two components: the main flux, which links the primary and secondary windings, and a leakage flux which links just the primary winding. The leakage flux is considered arising from a self inductance in series with an 'ideal' primary winding. The reactance of this inductance is termed the primary leakage reactance. The voltage drop across this reactance will lead the primary no-load current by 90 degrees which, when added to the voltage drop across the resistance of the primary winding, acts to reduce the back emf of the primary winding below the value of the applied voltage and cause it to lag.A similar explanation accounts for the an inductance and resistance in series with the secondary winding, when the transformer is loaded.
What type of voltage must be passed across a transformer?
A transformer must be connected to an alternating current (AC) supply of the correct voltage.
