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.
Circuits are used anywhere you want to have an electrical current flow. Without a circuit, you cannot have current flow. Without current flow, you cannot do any work.

In electronic circuits a capacitor is used to pass AC and block DC.
A ground fault circuit interrupter is the device used to de-energize the circuit.
No, a capacitor is a device that resists the change in electrical potential. It will take and hold a charge based on the value of the capacitor. It's most commonly used to "smooth" direct current or to pass a signal through a wire while passing very little current. There are some interesting circuits produced using capacitors, especially since the capacitors have so many unique properties.
Direct electric current cannot be used to operate D. Transformers.
Transformers are not used on DC circuits because they rely on a varying magnetic field to transform power.
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
To sense the current flow across the current transformers and to monitor the current ratings. In current transformers no voltage variations occurs. but in voltage transformers it is mainly used to increase or decrease the voltage value.
Some possible answers are: a battery (which produces direct current) or a generator of electricity generator, such as a dynamo (which produces direct current) or an alternator (which produces alternating current).
Not directly, as MC instruments are direct-current instruments, whereas instrument transformers only work on a.c.
A current transformer is used for measurement of alternating electric currents. Current transformers, together with voltage transformers are known as instrument transformers.
no direct current is not used in transformers. the reason is that, if dc is used, there would be no counter emf to oppose it in the primary winding. since the constant flux will be flowing in the dc, there would be no rate of change of flux. as a result, the total current will be applied at the primary winding only. this results in the burning of the total primary winding. ===================================== The practical application is: If transformer input is DC, transformer output is smoke.
transformers cannot amplify!
No transformers only work with AC.

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..
