Hi,
I'm doing a bit of coursework atm, and was confused as to how to calculate the flux density in an iron core of a Shell type transformer. The problem lies as where I take the area from.
Me and my mates have had a long chat about this and none of us are sure.
Do you take the area of the front, then take away the two air gaps, or the cross-section of the middle 'core'. or am i totally wrong?
