Question

The width of the space charge region at a p-n junction is reduced by applying a voltage bias over the p-n junction. What is the correct statement on both the bias voltage and the p-n junction?

The voltage is a forward bias and the diffusion of the majority charge carriers becomes more dominant.

The voltage is a reverse bias and the diffusion of the majority charge carriers becomes more dominant.

The voltage is a forward bias and the drift of the minority charge carriers becomes more dominant.

The voltage is a reverse bias and the drift of the minority charge carriers becomes more dominant.

Answer 1

A boat beguins on the best side of a river and heads straight east across the river with a speed of 1.9 Ft/s (relative to the water). the river water flows NORTH at the speed of 2.^ Ft/s (relative to the shore). The resultant veliocty of the boat ( relative to the shore) is approximately ___ Ft/s at __ degrees (-CCW from east)
