A transformer will convert the power to a different voltage, higher or lower depending on the requirement, while wasting very little of the power.
bride transformer
An Alternating Voltage is induced in the secondary winding. When connected to an external load, you will have an alternating current.
Electrical (alternating current)
As a transformer requires an alternating magnetic flux within its core, then the current flowing in its primary winding must be alternating.
Transformer is based on the principal of mutual inductance.Induction is produced due to sinusoidal wave form thats why we use Alternating current inspite of Direct current.
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.
No. A transformer has to have AC, alternating current, to work. And since it's alternating, it'll have a frequency.
In order to induce voltage as an output, a changing magnetic field is needed. To create a changing magnetic field in the transformer a changing current and that is an alternating current.
A transformer works with alternating current (AC). The primary coil of the transformer is connected to an AC power source, which creates a changing magnetic field that induces a voltage in the secondary coil.
No, it has to be an alternating current in order to work

Electrical (alternating current)
The basic principle of current transformer is same as that of the power transformer. Like the power transformer current transformer also contains a primary and a secondary winding. Whenever an alternating current flows through the primary winding alternating magnetic flux is produced, which then induces alternating current in the secondary winding. In case of current transformers the load impedance or "burden" is very small. Therefore the current transformer operates under short circuit conditions. Also the current in the secondary winding does not depend load impedance but depends on the current flowing in the primary winding.
That's called a transformer.
