Transformers are not used on DC circuits because they rely on a varying magnetic field to transform power.
What else can I help you with?
Are Transformers used in circuits with Direct Current?
No. Transformers are used in circuits with Alternating Current. Transformers work on the principle of a "changing" magnetic field inducing a current in a conductor, and you don't get that "changing" field with Direct Current.
What is an auto iris circuit?
Auto iris circuits are used in digital cameras.
Transformer are used in circuits containing both dc and ac?
No transformers only work with AC.
What types of transformers are used in an x-ray machine?
Auto bots.
How does a isolating transformer work?
Isolation transformers are used to isolate one circuit from another. Highly sensitive circuits may require isolation from high power circuits, for example.
What is transformers job?
It depends on the type of transformer:transmission/distribution transformers step up or step down system voltagesisolation transformers electrically isolate two systems without affecting their voltagesmatching transformers are used in electronic circuits for impedance matchinginstrument transformers step down voltages (voltage transformers) or currents (current transformers) for measurement or protection applications
What is the need of frequency in electrical power?
Transformers are used in AC circuits and won't work for DC. A frequency of 60Hz is popular in the USA.
Can instrument transformers be used to extend the range of a moving coil voltmeter?
Not directly, as MC instruments are direct-current instruments, whereas instrument transformers only work on a.c.
Why current transformers are used?
1) voltage level up-down2) voltage level down-up3) isolationAnswerBecause transmission would be impossible except at high voltages/low load currents due to enormous voltage drops that would otherwise occur, and these are achieved using Transformers..
What are some simple electronic devices that are used in electrical engineering?
Resistors, capacitors, inductors, transformers, diodes, transistors, integrated circuits, power sources are the basic building blocks.
What type of transformers are used to step down a voltage for general use and what type of systems are they classified as?
The transformer you describe is being used as a step-down transformer, and is classified as an electrical machine. The transformer could either be a mutual transformer, consisting of two, electrically-isolated coils, or an auto-transformer which uses a common coil between its primary and secondary circuits.
What is the applications of autotransformer?
power distribution Audio Railway
