Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
Yes the transformer effects the incoming frequency supply. This frequency is dependent on the core lamination of the transformer the weightier the core lamination the lesser will be the frequency we get and vice verse..
A: Absolutely while the voltage can be changed the current is limited by the design or kva
Frequency doesn't depend on either voltage or current.
the incoming voltage from the current source to the transformer is called primary voltage.....
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
The frequency is changed by varying its speed, and the the voltage is changed by varying its field current.
Voltage at secondary coil depends on differentiation of current at primary coil. In case of sinusoidal current, differentiation leads to sinusoid with same frequency, thus frequency does not change.

A sonometer is used to determine the frequency of alternating current. A step down transformer is used for the determination of frequency of A.C. because the voltage of the A.C. mains is 220V, which is dangerous. The step down transformer reduces this voltage to 6 volts.

If the transformer was designed for the specific frequency in use, it will step up or down voltage and current as it was designed to do. Transformers transform how power "looks" by increasing and decreasing voltage and current, while keeping power output equivalent to input (if you ignore the transformer losses).
Voltage must be changed by a transformer, and the alternating current changed to direct current by diodes. Each step has a loss of energy.
First we know that transformer is a statical electrical device that transfer electrical energy from one circuit to another circuit with out change its frequency .....it may be voltage or current is change simultaneosuly or separately .... and point is why does not change the frequency in the transformer because the there is no moving part in transformer....As we know that frequency is depends upon the rotation....
No, the current has to change for a voltage to be induced in the transformer.
A transformer steps the voltage of an electrical power supply up or down. The transformer must be correctly designed for the voltage and current levels that it is intended for. Only ac can be used with a transformer, which is designed to work at a particular frequency.
Maximum load current on a 140KVA, three phase transformer when the output voltage is 115 v phase to phase is: 140kva / sqrt (3) / 115 = 703 Amps. frequency does not matter here.
A transformer can only increase or decrease the voltage of an alternating current, and it is called step-up transformer or step-down transformer accordingly.
