Derive the relation
Relationship between α and β: Beta factor (β) is the current gain factor of a common emitter circuit is defined as ratio of change in collector current (IC) to the change in base current (IB) i.e.,
And alpha factor (α) is also called current amplification factor and is defined as ratio of change in collector current (IC) to the change in emitter current (IE) i.e.
Why is extended source use in Newtown ''s ring experiment?
Consider a circular loop in a magnetic field. The loop is made of elastic material with spring constant k. It carries a current I and has radius R when unstretched. We immerse it i
