How to calculate transformer core weight 

I think ya size of bobin ma sa Lia hu ga... ka kitnay by Kitna ka bobin ha

Sir Ge 7 number sy kon see matlab

Yane 7,8 9 E kes chez ki number hi core ki ya one's pes ke ya pir matlab nahe saja

Kyuki 5 inch ka transformer ka stack ( motai ) hai

Bobin size

5 inch yahan bobbin ki size hi hota hai

Uske volt, aur amp ,ghat, badh sakte hai

Jyada current ke liye ya fir jyada power ke liye 8 no core lena sahi hota hai 7b se. Kyunki 8 no core ki window space 7.7 sq inch hota hai jab 7b me sirf 4.7 sq inch hi hota hai to juada mota wire 8 no core me dalana sakta hai. Aur window space aur crossectional product se hi transformer ki power hi derive hota hai

Ye video core weight ki h, copper weight nhi

Wo sirf electrical dept ko bhi sayad pata nehin bhi hoga

Lohe ki pattiye jo hoti hai E type aur I type ki jise dala jata hai transformer ki bobin me

But why , want to know e and I core weight separately that you get I and e core in combination
