What is the formula for window area of the transformer? |
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 |
Answer» C. window area = output power / 3.33 * frequency * magnetic field * window space factor * current density * area of cross section of the core *103 | |
