A transformer has 10000 turns of wire in the secondary and 100 turns in the primary the transformer is connected to a line voltage of 120 volts.the output voltage will be?

The voltage and current are stepped in proportion to the turns ratio, 10000 / 100. I am assuming the 120 volts is connected to the secondary. Then:
120 volts * (10000/100) = 12000 volts on the primary side.
The current will change in opposite way, 100 / 10000

∙ 13y agoIf Input voltage = 25 V, Primary turns = 100 & Secondary turns = 1000
Input Voltage / output voltage = Primary turns / Secondary turns
25 / OV = 100 / 1000
25 X 1000 = OV X 100
OV = 25 X 1000 / 100
OV = 250
Output Voltage = 250 V

Why is the wattmeter connected at the primary side of the transformer?
In general, you can install a wattmeter on the primary or the secondary side of a transformer (it depends what you are trying to measure). But if you are conducting an open- and short-circuit test (to find the transformer's losses), then the wattmeter is connected to the primary side because you want to measure the total (primary + secondary) losses and that is only achievable from the primary side.
When secondary coil is open there is no current in the primary coil WHY?
I am assuming the question is about the power / distribution transformer and not the current transformer. The primary current is a function of load connected on secondary. With the open secondary, there is no load, no current, it is open circuit. Hence no primary current. However there is always some small amount of no load current in the primary winding.
How To Test An 230vac -230vac Isolation Transformer?
Make sure there is no voltage measured between line of secondary and neutral of primary. I.e. neutral of primary and secondary are not connected by any means.
Why load is always connected to secondary of transformer?
b'coz at the secondary side large amount of current flow by recarding of active component or other ckt. which is connected to the secondary side so that ckt. is not damage or burned by flowing large amount .. load is connected at the secondary side .AnswerThe 'primary' winding of a transformer is, by definition, whichever winding is connected to the supply, whereas the 'secondary' winding is whichever winding is connected to the load. This does not mean that a load MUST be connected to a transformer, as it will work 'off load' -that is, with no load connected- without any harm.
What are the two coils in a transformer?
primary and secondary coilsAnswerPrimary and secondary windings.
The primary winding in a transformer is connected to the what?
The primary winding of a transformer is connected to the supply, while the secondary winding is connected to the load.
What are the primary winding and secondary winding of a transformer?
The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. The terms, 'primary' and 'secondary' are unrelated to voltage levels.
What is the term for the transformer winding to which the load is connected?
The load is connected to the transformer's secondarywinding, while the primary winding is connected to the supply. The terms, 'primary' and 'secondary', do NOT relate to voltage levels.
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.
Is there more current in the primary or secondary winding of a transformer?
The terms, 'primary' and 'secondary', describe how a transformer is connected and his nothing to do with which is the lower- and higher-voltage winding.The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. So, for astep-up transformer, the secondary winding is the higher voltage winding, whereas for a step-down transformer, the secondary winding is the lower voltage winding.For a loaded transformer, i.e. a transformer whose secondary is supplying a load, the higher-voltage winding carries the smaller current, while the lower-voltage winding carries the higher current.
Why is the wattmeter connected at the primary side of the transformer?
In general, you can install a wattmeter on the primary or the secondary side of a transformer (it depends what you are trying to measure). But if you are conducting an open- and short-circuit test (to find the transformer's losses), then the wattmeter is connected to the primary side because you want to measure the total (primary + secondary) losses and that is only achievable from the primary side.
What will be the unloaded voltage if the primary is connected to 500V on a transformer that has 200 turns on the primary and 100 turns on the secondary?
If that is 500VDC, the secondary will have 0VDC. if that is 500VAC, the secondary will have 250VAC.
What is winding transformer?
A winding is the name given each of the coils wound around the transformer's core. A basic transformer has two windings, termed the primary winding (connected to the supply) and the secondary winding (connected to the load).
How can you distinguish the primary from secondaty side on a transformer?
Whichever winding is connected to the supply is the primary winding; whichever winding is connected to the load is the secondary winding.
Can infinite voltage be given at transformer primary?
no, infinite voltage can't be given to the primary of the transformer....if the secondary is connected to the load, then over voltage will damage the load, if secondary is open circuited, then the infinite voltage can breakdown the transformer internal insulation,
Is 3 phase star transformer has more winding than delta?
The # of windings in a transformer are based on the primary and secondary voltages the transformer is rated for not the way the windings are connected.
How can you identify which one is step up or step down transformer?
A transformer has two windings, termed the 'primary winding' and the 'secondary winding'. The primary winding is the winding connected to the supply, while the secondary winding is connected to the load. The secondary voltage of a 'step up' transformer is higher than the primary voltage; the secondary voltage of a 'step down' transformer is lower than the primary voltage. The simplest way to determine whether a transformer is a step up or step down, is to measure the primary and secondary voltages. If you are simply looking at a transformer, then the transformer's insulated bushings will give you a clue -the higher voltage bushings are much bigger than the lower voltage bushings. If you have access to the inside of the transformer, then the higher voltage windings are thinner and have a greater number of turns than the lower-voltage winding.
