Class XI - XII (Physics ) tuition at pallavaram

Ans: C (A) and (B) both in the same way. We know that the cross sectional area is inversely proportional to the resistance of the conductor. In magnetic circuits, reluctance is analogues to the resistance. Hence, the resistance and reluctance would affect in the same way.

Class XI - XII (Physics ) tuition at pallavaram

Ans is : C resistivity (row) = (Resistance*A)/l. Hence R = (row*l)/A. From this equation, we know that the cross sectional area is inversely proportional to the resistance of the conductor. In magnetic circuits, reluctance is analogues to the resistance. Hence, the resistance and reluctance would...
