The Difference Between
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?
How many primary turns and secondary turns in 12 volt 1 amps stepdown transformer?
What is the difference between stepdown and stepup transformers?
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.
Does 110 volts cost more if uses stepdown trasformer?
How many turns on secondary side of transformer with comparison to the primary side?
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.

Can a 240v - 110v stepdown transformer be reversed to supply from180V stepping up to 240Volts?
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.
Is there a way to install a 120V light on a 277V circuit?
A transformer is used to step down a voltage of 11kv to 220 volts. Given that the primary coil has 3200 turns what is the number of turns on the secondary coil?
When a transformer steps down a power source what will remain the same the frequency the voltage or the current or none of these?
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
How do you convert 24volts to 12 volts?
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.

Asked in Electrical Engineering
Why starting currrent is higher in 3 phase id motor than 3 phase transformer?
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.
