When a p-n junction diode is forward biased
A)a current does not flow through it.
B)a current flows through it from the p-side to the n-side.
C)a current flows through it from the n-side to the p-side.
D)a current flows because holes and electrons are traveling in opposite directions away from the junction.
E)a current flows because holes and electrons are traveling in the same direction towards the junction.

When a p-n junction diode is forward biased, a current flows through it from the p-side to the n-side. This is because the forward bias causes the depletion region to narrow, allowing electrons from the n-side to diffuse into the p-side and holes from the p-side to diffuse into the n-side.
