The current in a transformer is made by inducing voltage across the primary coil.

• The primary coil of a transformer is connected to an alternating current (AC) source.

• The alternating current in the primary coil creates a changing magnetic field.

• This changing magnetic field induces a voltage across the secondary coil.

• The induced voltage in the secondary coil causes a current to flow through it.

• The current in the secondar...read more

DC shunt motors are a type of direct current motor that have a parallel field winding and a series armature winding.
