Why depletion region is called potential barrier?
Why depletion region is called potential barrier? The region is created because of the depleted ions, and hence it is called the depletion region. The depletion region acts as a barrier and opposes the flow of charge carrier. The value of barrier potential lies between 0.3 – 0.7V depends on the type of material used. […]
Why does magnesium mass increase after burning?
Why does magnesium mass increase after burning? When the magnesium is heated up, the total mass increases because magnesium reacts with oxygen, forming magnesium oxide ( so it supported the hypothesis). The increased mass is because of oxygen.
