Question

When the p-side and n-side are joined, in which direction do electrons diffuse?

Options

• From the n-side to the negative terminal

• From the p-side to the positive terminal

• From the p-side to the n-side

• From the n-side to the p-side

Answer 1

Electrons diffuse from the n-side to the p-side when the two sides are joined. Holes diffuse in the opposite direction, from the p-side to the n-side.
