How does current flow in a transformer?
a transformer (two windings) is a kind of transducer in which current flowing through the primary winding creates a magnetic flux that passing through secondary winding results in current flowing through the load. Shortly current in primary winding produces current and voltage in the secondary winding.
What is the relationship between primary and secondary current of a transformer?
Transformer current calculations: The primary current is equal to the product of the secondary voltage and secondary current divided by primary current. The secondary current is equal to the product of the primary voltage and primary current divided by secondary voltage.
What is primary and secondary in CT?
A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers.
Why does current flow in the secondary coil?
A coil is a reactionary device, not liking any change! The induced voltage will cause a current to flow in the secondary coil which tries to maintain the magnetic field which was there. The fact that the induced field always opposes the change is an example of Lenz’ law .
What current flows in the transformer primary when the secondary is open?
The current that flows in the primary winding of a transformer when it’s secondary is open is only the current that supplies for no load losses and setting up the magnetic flux in the core, hence the name, no load current.
What current flows in the transformer primary when the secondary is open what is its function?
Does current flow in transformer core?
Transformers consist of two windings, primary and the secondary. When the voltage is connected to the primary coil , the AC current flows flows through and this current creates a magnetic field which passes to the secondary winding via the core of the transformer.
