The secondary voltage (output voltage) of a transformer depends on the turns ratio of the transformer, and is limited by the practical insulation levels of the secondary winding, so can be very high indeed. Power Transformers used in electricity transmission systems have secondary voltages in the range of hundreds of kilovolts.

∙ 11y agoThis sort of depends on your situation, but I would assume that in general maximum output voltage would be obtained when all resistance is removed from the circuit. I hope this helps.

What is the difference between variable transformer and ordinary transformer?
Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.
Why the transformer connected on inverter output?
A transformer is connected to the output of inverter in order to step up the AC voltage output.
Why might the unloaded output voltage of a transformer be higher than its rms of 12.6v?
Because the windings of transformers have resistance, the primary and secondary currents will cause voltage drops. To compensate for the drops, the transformer may have been designed to have a higher than specified output voltage when there is little or no output current. The no load output voltage typically is only slightly greater than the specified voltage. Before measuring the output voltage, measure the input (line) voltage. If it is not as specified for the transformer, calculate its effect on the output.
What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a full rectifier circuit with a filter capacitor?
25.46V assuming output of transformer is pure sinewave.
What determines the output voltage and the current of a transformer?
The ratio of output windings to input windings determines the ratio of output voltage to input voltage. The ratio of current is the inverse.
What is a variable transformer?
A variable transformer is capable of changing its output voltage from 0 to maximum output or over a specific range. It is also named an adjustable transformer.
What is the difference between variable transformer and ordinary transformer?
Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.
What is voltage regulation of Transformer?
The change in output voltage from no load to full load defines the voltage regulation of that transformer.
How much output voltage is there if input voltage from a transformer is 32v?
It depends on the turns ratio of the transformer.
What are the output voltage and current of a transformer determined by?
The secondary (output) voltage is determined by the primary voltage and the turns ratio of the transformer. The secondary current is determined by the secondary voltage and the load resistance.
Why the transformer connected on inverter output?
A transformer is connected to the output of inverter in order to step up the AC voltage output.
Why does your 24 volts transformer get hot then burn out?
A transformer gets hot if it is run at excessive voltage or excessive current. Either of those two would cause it to overheat. <<>> It sounds like the load on the secondary is greater that what the transformer can supply. A transformer is wound for a specific amperage output at a specific voltage. This is stated on the transformer as a VA or in larger transformers as KVA. If you divide the 24 volts into the VA listed on the transformer you will get the maximum amperage value of the transformer. If the device that you are connecting to the transformer is greater in amperage draw that what the transformer can supply, this will cause the heating effect and if left connected eventually burn the transformer out. A fuse should be installed in the secondary 24 volt output, rated at the maximum output of the transformer. This will limit the transformer to its manufacturer's recommended current output.
How many amps does a 600 watt low voltage transformer box pull?
The transformer itself does not pull current. Whatever you connect to the transformer pulls current. Whatever the output voltage of the transformer is, divide that into 600 and you get maximum current possible without burning up the transformer. At 24V that's 25 amps.
What is the Name of the transformer in which the output AC voltage is less than the input AC voltage?
It is a step-down transformer.
What is the use of single phase variac in circuits?
A variac a variable auto-transformer, allowing the output voltage to be adjusted from zero up to a maximum voltage, which might be 20% greater than the supply voltage.
What is a full load current in single phase transformer?
It is the rated maximum current that can be taken from the transformer. This is equal to the VA rating divided by the output voltage. So a 6 kVA 240 v transformer would have a maximum current rating of 6000/240 or 25 amps.
Why might the unloaded output voltage of a transformer be higher than its rms of 12.6v?
Because the windings of transformers have resistance, the primary and secondary currents will cause voltage drops. To compensate for the drops, the transformer may have been designed to have a higher than specified output voltage when there is little or no output current. The no load output voltage typically is only slightly greater than the specified voltage. Before measuring the output voltage, measure the input (line) voltage. If it is not as specified for the transformer, calculate its effect on the output.
