If a centre tap transformer rated as 12V-0-12V 1Athen what will be the secondary current of that perticular transformer?
Manilaldesai
The output voltage of a transformer is not connected to the maximum rated current. You state that the transformer is rated at 12-0-12 at a current of 1A, therefore the maximum (rated) current on the secondary would be 1A. Normally, Transformers are rated in VA (volt amps) which is simply voltage x current, the voltage across the two 12v terminals would be 12+12 volts, making the rating of the transformer 24VA.

What is the secondary rating of a 50KVA transformer?
The secondary current is determined by the load, not by the transformer. For example, if the secondary voltage is 50 V and the load is 100 ohms, then the secondary current will be 0.5 A. If the load is 25 ohms, then the secondary current will be 2 A. It is important that a continuous secondary current doesn't exceed the rated secondary current of the transformer.
What is principle of Current transformer?
why does have to short-circuit secondary wire of current transformer ?
What is the function of the primary current when the secondary winding of the transformer is open?
When the secondary of a transformer is opened, there is no longer any load on the transformer. There will be some current flowing in the primary winding, which is needed to induce the voltage in the secondary. This primary current is referred to as the "no load" current, and is indicative of the core losses in the transformer.
When working on a current transformer the secondary windings must be?
When working on a current transformer the secondary windings must be shorted. <<>> Properly loaded
What is the standard output current of a transformer when connected to an ac?
There is no 'standard' output current from a transformer. The secondary (output) current depends on the load, and should not exceed the rated secondary current. To find the rated secondary current, you divide the transformer's rated volt amperes by the rated secondary voltage. The above cited answer need more descriptive ; a) V/Z = I, b) V/Z = I + Magnetizing current of the transformer taken from Primary side of the transformer.
What is the secondary amps of 315kva transformer?
The secondary current is determined by the load, not by the transformer. But the load current mustn't continuously exceed the rated current of the secondary winding. To determine the secondary rated current, you need to know the rated secondary voltage of the transformer, and divide 315 kV.A by this figure.Incidentally, the correct symbol for 'kilovolt ampere' is 'kV.A', not 'kva'.
When 440 volts and 300 amps is given as an input to the transformer the output obtained is 11 kva in this secondary current will decrease or not?
Your question reveals a misunderstanding of how a transformer works.The primary current of a transformer is determined by the secondary current, not the other way around. When the secondary voltage is applied to a load, a secondary current flows, and its value is determined by the secondary voltage and the load impedance. This secondary current then determines the value of the primary current.
Does a transformer increase amps?
The primary current is determined by the secondary current, not the other way around. For example, a step up transformer will step up the primary voltage in proportion to the turns ratio of the transformer. Any secondary current is then determined by the secondary voltage and the load, NOT by the primary current. The primary current is then determined by the secondary current in proportion to the reciprocal of the turns ratio.
In a transformer what induces a current in the secondary coil?
The current flowing in the primary generates a magnetic field which induces a current in the secondary winding.AnswerNo current is induced into the secondary winding of a transformer. What is induced is voltage. Current will only flow in the secondary winding if it is connected to the load, and it is the load that determines the current, not the primary current.
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.
What is current carrying for 2200kVA transformer?
Presumably you are asking about the rated secondary current of a transformer rated at 2200 kV.A?This depends on the rated secondary voltage. You divide the rated apparent power of the transformer by the rated secondary voltage.Of course, the actual current depends on the load.
How is current controlled in welding transformer?
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
