Vedclass · Answer

(A) In a transistor,the current is carried by charge carriers. In an $n-p-n$ transistor,the majority charge carriers are electrons,whereas in a $p-n-p$ transistor,the majority charge carriers are holes.Electrons have higher mobility compared to holes because they are lighter and interact less with the crystal lattice.Due to this higher mobility,electrons can move faster through the base region,allowing for higher current conduction in $n-p-n$ transistors compared to $p-n-p$ transistors.Therefore,both Assertion $A$ and Reason $R$ are true,and $R$ is the correct explanation of $A$.
