why we use iron corn in transformer instead of wooden core

Answer Posted / nitin shridhar

Just Compare
Electrical circuit Vs Magnetic Circuit.

In Electrical
Voltage= Current* Resistance

In Magnetic
MMF= Flux * Reluctance

We use Copper wire in Electrical circuit as its Resistance is low. Similarly We use Iron as Core Because its Reluctance is small.
