DC current cannot be used in a transformer only AC will work. A transformer needs the continual build and collapse of the magnetic field to keep the iron core from reaching saturation. Only alternating current will transfer power through a transformer.

What is a curect transformer?
A 'current transformer' is a type of transformer which, together with a 'voltage transformer' (or 'potential transformer' in N America), is classified as being an 'instrument transformer'. It is used to reduce large currents to smaller currents which can be measured safely, and to isolate the primary circuit from the secondary circuit for the purposes of safety. Current transformers are also used to drive protective relays used in high-voltage protection systems.
What does a buck boost transformer do?
A buck boost transformer is a type of transformer that is used to make adjustments to the voltage applied to alternating current equipment. These transformers are typically used in back up supplies or in tanning beds.
Can I connect current transformer in series?
CT(Current Transformer) is used to measure current flowing in the circuit. Current can be fully drawn or sensed in series condition. That's why , it is connected in series. In parallel , the current is divided; and hence the total current cannot be measured)
Can a current transformer be used for current amplify?
transformers cannot amplify!
What is the difference between power transformer and instrument transformer?
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
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 type of device is used to increase or decrease the voltage of an electric current?
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
Type of transformers used in gas insulated substation?
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.

Explain differancnce between instrument current transformer and measuring current transformer?
Current transformer is a device used to measure the flow of current through a power system and the measured current is inputted to a protective relay system. It is used to detect system malfunction. Current transducer is a device used to measure AC and DC current based on the halt-effect technology.
How is current controlled in welding transformer?
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
What device can be used to increase current in a DC circuit?
Transformer or instrument transformer. It can increase and decrease current output.
Can you use transformer with your 110 aircon?
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.
What type of device is used to increase to decrease the voltage of an electric current?
In an alternating current circuit the voltage can be stepped up ordown efficiently with a transformer.
