A step-down transformer has 525 turns in its secondary and 12500 turns in its primary If the potential difference across the primary is 3510 V what is the potential difference across the secondary?

Depends on what the voltage is going from - and to.

A step-down transformer produces a secondary voltage that is lower than its primary voltage, while a step-up transformer produces a secondary voltage that is higher than its primary voltage. The primary voltage is the voltage applied to the transformer, whereas the secondary voltage is the voltage supplied by the transformer. It's the transformer's turns ratio that determines whether it is a step down or step up transformer: i.e. the ratio between the primary and secondary windings. If there are less turns on the secondary winding, then it's a step down transformer; if there are more turns on the secondary winding, then it's a step-up transformer.

If you have to pay for the stepdown transformer, yes. If that is provided free, there is a small loss of energy in the transformer, maybe about 5%, and it depends on whether the meter is installed before or after the transformer.

the maximum power it will supply

You would use a stepdown transformer.

It depends on the type of transformer. If it is a step up transformer the number of turns in secondary side is higher than primary. Stepdown means it will have fewer number of windings on the secondary side turns when compared with the primary side. An isolation transformer has the same number of windings on the primary as the secondary. The ratio of the windings is proportional to the increase or decrease in the secondary voltage. For example, twice the windings doubles the voltage and 1/2 the windings halves the secondary voltage. The isolation transformer is denoted as 1:1 and has the same voltage on the secondary as the primary. The ratio of secondary turns to primary turns is the same as the ratio of secondary voltage to primary voltage. e.g. if the secondary to primary turns ratio is 1/10, then the secondary voltage will be one tenth of the primary voltage.

It is used to step up the voltage in order to transmit it a long distance where it goes into a stepdown transformer and then into your home .

A 150kVA transformer, stepdown from 4160V to 600V, 3 phase, will have 20.8A on the primary side and 144.3A on the secondary side assuming the TX is 100% efficient, they are usually 2-3% losses to noise and heat etc.

The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.

Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.

This is a 2:1 ratio stepdown transformer. With an output of 120 volts the primary is 240 volts input. See related links for an excellent description of transformers.

a stepdown transformer is used to reduce the voltage and limit the available amperage

Transformers can be reversed but their ratio remains the same. In this case a 240 to 120 volt step down transformer has a ratio of 2:1. By reversing the transformer and using 180 volts on the secondary side, there would be a potential of 360 volts on the primary side of the transformer. Also by using the higher voltage on the secondary side, stepping up will drive the primary side voltage above what the insulation factor that is recommended which is 240 volts. A 240/120 v transformer is designed to run at that voltage, and it is dangerous to operate it at a significantly higher voltage because there will be appreciably higher magnetic flux in the iron core, leading to higher power dissipation and a potential fire hazard. For a great explanation of how transformers operate, see related links below.

A step-down transformer U really don't need a step up or stepdown transformer You need a source capable to run your LED it can be a swithcing power supply for istance a battery

Your 11 kv to 220 volts represents a 50 to 1 stepdown. (There is 50 times more voltage in the primary than in the secondary.) You'll have to have a 50 to 1 turns ratio. That means 1/50 of the number of turns in the primary will be in the secondary, and that is 64 turns.

The frequency remains the same as one cycle in the primary corresponds to one cycle in the secondary. The stepdown voltage on the secondary as a ratio of the voltage on the primary will be the same as the ratio of turns in the primary to turns in the secondary. The current in the secondary depends on two things: the current that the load is taking at the lower voltage of the secondary and the relative thickness of the wire in the secondary to the thickness of the wire in the primary. ANSWER: A transformer does not step up/down a power source ever it does however step up/down the voltage related to the primary. A typical transformer will always have an efficiency loss. The frequency on the output will remain the same as the input. It is not true that the big wires will give you more current that would be true only if the iron core is increased accordingly. otherwise saturation will occur

If you want to convert 24v AC into 12v Ac, it's simple. Just get a transformer to convert 24 volts into 12 volts. This is called a stepdown transformer. If you want to convert 24v DC into 12v DC, it's more complicated. First you have to change the 24v DC into 24v AC by a switching converter that changes DC into AC. Then you would use a stepdown transformer as in the former example. Once the 24v AC is converted to 12v AC, then you use a rectifier bridge to change the 12v AC into 12v DC.

USE STEPDOWN TRANSFORMER: PRIMARY INPUT: 277 VAC SECONDARY: 110 VAC OR : THERE ARE AVAILABLE AVR'S - AUTOMATIC (ELECTRONIC) VOLTAGE REGULATORS WITH WIDE VOLTAGE RANGE IN THE MARKET; INPUT: 85 VAC TO 290 VAC OUTPUT: REGULATED (CONSTANT) OUTPUT: 220VAC AND 110 VAC

To convert 415 volts to 220 volts, you use a stepdown transformer of an appropriate rating. Since this is a three phase circuit, you need a three phase transformer, or three one phase transformers.

current is decreased Depends of the circuit or device: in a stepdown transformer: power in= power out, V x I = V x I , Increase voltage in (power remaining constant) you current output will increase.

CLARIFICATION AND ANSWER: 1. STARTING CURRENT PRODUCED ONLY BY ITS LOAD NOT SOURCE(SAY STEPDOWN TRAFO) 2. IF THE INDUCTION MOTOR IS THE ONLY LOAD OF THE STEP DOWN TRANSFORMER (SOURCE)-THE READING WILL BE AND SHOULD BE THE SAME IN THE SECONDARY SIDE UNLESS YOUR AMMETER IS IN THE PRIMARY SURELY WILL READ LOWER BUT POWER CONSUMPTION REMAINS THE SAME. 3. IT ALSO DEPENDS ON THE RATING OF THE MOTOR LOAD AND THE TYPE OF STARTING METHOD USED THAT YOU CAN MEASURE STARTING CURRENT.

In short, probably. Transformers step power up or down by a multiplicative factor based on the number of turns in the two transformer coils. Therefore, if you put more voltage in you're going to get a proportional increase in the voltage out.

Transformers are necessary to stepup or stepdown voltage levels so that transmission of power is convenient. without stepup/stepdown voltage level according to our requirement losses will be very high and transmission and usage of power is not feasible.
