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.

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.
What device can be used to increase current in a DC circuit?
Transformer or instrument transformer. It can increase and decrease current output.
Can transformers be connected in series?
A: Absolutely but the output for a power transformer will be less. the phases can also be out of phase on the output yielding no output at all.
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.
How many turns does a transformer need to take 137V on the primary and produce 47V on the secondary with output current of 20A for a 5kVA stabilizer?
You will need a 3:1 ratio transformer. An output current of 20 amps and a secondary voltage of 47 volts, results in a transformer rated at 940 VA.
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.
What are the limitations of power supply?
Power limitation transformer circuit structure of power supply, including: an electromagnetic interference filter unit, a rectifying unit, a power factor correction section, a transformer having a primary input terminal and secondary input terminal, a pulse controlling unit connected with the secondary input terminal of the transformer, a primary power limitation circuit and at least one secondary power limitation circuit, an output current controlling unit and an output voltage controlling unit. The input terminal of the output current controlling unit is connected with the secondary output terminal of the transformer. The primary output terminal and secondary output terminal of the output current controlling unit are respectively serially connected with the primary and secondary power limitation circuits. The input terminal of the output voltage controlling unit is connected with the secondary output terminal of the transformer. The output terminal of the output voltage controlling unit is connected with the secondary power limitation circuit for controlling the magnitude of the voltage and current of the primary and secondary power limitation circuits so as to control the output power.
What is the output current of a 480 Volt primary 208 volt secondary - 3 phase transformer?
You need to mention the Load connected to find the current.
What device can be used to increase current in a DC circuit?
Transformer or instrument transformer. It can increase and decrease current 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.
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.
Can transformers be connected in series?
A: Absolutely but the output for a power transformer will be less. the phases can also be out of phase on the output yielding no output at all.
Could you provide me with the inside diagram of a current transformer?
A current transformer is just a transformer designed to dutifully give an output related to turns ratio 1:xx.
How do you multiply current transformer output?
There are many ways but never can you multiply the power. <<>> A current transformer is specifically designed, by amp turns, to only output 5 amps. Meters that are connected to CT's have a full range deflection (scale) of 5 amps. To do what you are asking seems pointless as there are no meters with 10 amp full scale deflection.
Can I connect current transformer in series?
CT(Current Transformer) is used to measure current flowing in the circuit. Current can be fully drawn or sensed in series condition. That's why , it is connected in series. In parallel , the current is divided; and hence the total current cannot be measured)
What remains unchanged in transformer action?
In a standard transformer, the ratio of input volts to output volts remains constant.
Can you use a step up transformer 110220 with output of 16 kva?
Yes, but your input current is going to be high at 133 amps. The output of the transformer is not going to be 16 KVA, that is the rating of the transformer.
