Not at all sure about core, but there are 7 zeros in 178379 crore.
There are 21 zero in 3 core. 1 core = 7 zero so 7x3=21.
7 zero's are there in 1 core
A core need not have any zeros.
Not sure about 19 core, but there are seven zeros in 19 crore.
Steve Mandanda scored zero goals for Olympique de Marseille.
In my experience, the zero sequence of transformers is not calculated, it is directly tested following ANSII/IEEE guidlines for Z1no, Z2no, and Z1ns tests (for three phase, three winding transformers). Rough estimations of zero sequence impedance can be determined based on the positive sequence and core form of the transformer. A Shell type core will have a zero sequence of ~100% the positive sequence because the flux stays in the core / follows the same path as it does for positive sequence currents. For a core type, the zero sequence will be ~80-90% typically, because the flux must travel outside the core. This is for three winding transformer.
There is one zero in the number zero.
When large magnetomotive force is applied to the core and then removed. The flux in the core doesn't reach zero. Instead, a magnetic field is left behind in the core. This magnetic field is called residual flux in the core. MOHSIN BB-EE-NED
The coupling between windings will be nearly zero, resulting in nearly zero output. In short, your transformer's not going to work.
