Question: What is the formula for window area of the transformer?
Options
A : window area = output power * 2.22 * frequency * magnetic field * window space factor * current density * area of cross section of the core *103
B : window area = output power / 2.22 * frequency * magnetic field * window space factor * current density * area of cross section of the core *103
C : window area = output power / 3.33 * frequency * magnetic field * window space factor * current density * area of cross section of the core *103
D : window area = output power * 3.33 * frequency * magnetic field * window space factor * current density * area of cross section of the core*103
