What does a transformer do to current and voltage?

the incoming voltage from the current source to the transformer is called primary voltage.....

In case of current transformer the voltage is constant. we can step up or step down the current rating. In case of Voltage Transformer the Current is constant. We can step up or step down the voltage ratings.

No, the current has to change for a voltage to be induced in the transformer.

A current transformer is a transformer that takes a ratio of primary current, and delivers this ratio to the secondary. The voltage across the primary will be insignificant, and the voltage across the secondary is dependent upon the resistive burden put across it (since the current is a constant ratio of the primary current). A voltage transformer is a transformer that takes a ratio of primary voltage and steps this down to a specific secondary voltage. Primary current is typically very small and secondary voltage is typically very small. A power transformer is a voltage transformer that is designed for "large" primary and secondary currents.

In common with most electrical circuits, when the voltage supply to a transformer is increased, the current through the windings also increases. However, when the current drawn from the transformer increases (with the supply voltage unchanged), the voltage output from the transformer will be reduced.

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.

Usable working voltage, because a transformer was used and sized to get a voltage and at a current that you need. Another Answer 'Secondary voltage' and 'secondary current'!

A current transformer step downs the current in a power circuit to a lower amperage. A voltage transformer steps down the voltage in a power circuit, typically to 110 volts AC for residential and business use.

The term 'constant voltage transformer' is used to differentiate the operation of transformers that are intended to change voltage levels, from those intended to change current levels -a current transformer (CT), for example, is termed a 'constant current transformer'.

The incoming voltage from the source to the transformer is called primary voltage.

Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.

The input voltage to a transformer is called "primary".

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.

You get alternating current, AC, from a transformer.

A transformer can be used to change the voltage to an appliance. The voltage rating of the transformer should be right for the voltages used, and the current rating of the transformer should not be less than the current drawn by the equipment.

A step up transformer increases the voltage and decreases the current, however a step down transformer will decrease the voltage and increase the current

It is called a transformer. No, not the robot type. A transformer increases or deacreases the voltage in an electric current.

Current transformers are not voltage transformers. Current transformer are used for metering or protection purposes, with single turn primary. Generally the secondary current is either 1Amps or 5Amps.

A current transformer is a donut (toroidal) shaped transformer. You use it to measure current (expressed in amperes). You run your wire to be measured through the transformer and it produces a variable output based on the current. A potential transformer is basically a high ratio transformer that is used to measure voltage on high-voltage lines. For example: They will use a 10:1 ratio potential transformer to convert 4160v to 416v. Then they can measure this lower voltage with a meter. The meter then applies a user programmed multiplier (10) to this number to calculate the voltage.

I depends on the voltage.

Take the VA of the transformer and divide it by the output voltage.

A step-up transformer.

The transformer itself does not pull current. Whatever you connect to the transformer pulls current. Whatever the output voltage of the transformer is, divide that into 600 and you get maximum current possible without burning up the transformer. At 24V that's 25 amps.

A step-up transformer steps up voltage.

A transformer must be connected to an alternating current (AC) supply of the correct voltage.
