What else can I help you with?
What type of transformer connection can be used when it is necessary to rectify alternating current into direct current with a minimum of ripple?
bride transformer
Would you expect to find an alternating or direct current in the secondary coil of a transformer?
An Alternating Voltage is induced in the secondary winding. When connected to an external load, you will have an alternating current.
What kind of energy source does a transformer use?
Electrical (alternating current)
What is type of current that transformers require to operate?
As a transformer requires an alternating magnetic flux within its core, then the current flowing in its primary winding must be alternating.
Why must you use ac current for transformer?
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 the voltage of an alternating 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.
Is transformer work without freqency?
No. A transformer has to have AC, alternating current, to work. And since it's alternating, it'll have a frequency.
Why does a transformer require alternating current?
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.
Which type of current does a transformer work with?
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.
Is power transformer is constant current device?
No, it has to be an alternating current in order to work
A devise that increases or decreases the voltage of alternating current?
TRANSFORMER
What type of transformer connection can be used when it is necessary to rectify alternating current into direct current with a minimum of ripple?
bride transformer
What is an apparatus for reducing or increasing the voltage of an alternating current?
A transformer

Electrical (alternating current)
Fundamental principle of current transducer?
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.
A device that increases the voltage of an alternating current is called?
That's called a transformer.
