Different transformer cores with different primary currents with and without air gaps are as shown below
P: To have the equal constant flux in both transformers, I1 should be greater than I2
Q: To have the equal constant flux in both transformers, I1 should be lesser than I2
R: The magnitude of I2 will be more by considering the fringing effect compared to the non-fringing effect for constant flux.
S: The magnitude of I2 will be less by considering the fringing effect compared to the non-fringing effect for constant flux
