The voltage induced into the secondary winding will be lower than the voltage applied to the primary winding. The primary winding being the winding connected to the supply, while the secondary winding is the one connected to the load.

∙ 10y agoThe terms, 'step down' and 'step up', are applied to Transformers. Transformers whose secondary (output) voltage is lower than their primary (input) voltage are termed 'step down' transformers; those whose secondary voltage is greater than their primary voltage are termed 'step up' transformers.

What type of transformer is found outside a residential house?
Stepdown Transformer.
What is 660VA for stepdown transformer capacity?
the maximum power it will supply
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
What is the main different between the power transformer and voltage transformer?
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
What kind of transformer do i use to run LED?
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
What happens if a 208VAC primary voltage is connected to a 240VAC stepdown transformer to 208VAC?
The transformer will act as a step down transformer in the ratio of 240 to 208. This will reduce the 208 input to 180.
What does a step up transformer do at a powerplant?
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 .
What happens to voltage when current is increased?
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.
What type of transformer is found outside a residential house?
Stepdown Transformer.
Does 110 volts cost more if uses stepdown trasformer?
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.
What is 660VA for stepdown transformer capacity?
the maximum power it will supply
You have 480 volts coming into a stepdown transformer that is set for 440 volts incoming power would this cause your output voltage to be higher than 120 volts?
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.
Can a 240V - 110V stepdown transformer be reversed to take a primary load of 180V to secondary 240Volts?
No
What happens when a transformer is operated at no load with high voltage?
It depends on how much voltage you have applied. If you apply rated voltage nothing happens only core losses will be there on the transformer nothing will happen apart from that. If you go on increase the voltage core losses will increase and transformer will get heated up. After attaining the breakdown voltage of insulation, insulation in the primary and secondary will fail and the coils will get short circuited then the coils will burn.
What happens when a light bulb is connected to the output coil of the transformer?
Assuming that the voltage rating of the lamp matches the rated secondary voltage of the transformer, the lamp will operate at its rated power.
What is a transformer that increases voltage?
A transformer that increases voltage is a step-up transformer.
How a transformer is very useful in ac supply?
Transformer is the only device which is capable to stepup or stepdown an ac signal. That's why its used widely in ac supply.
