Diodes are non-linear devices. This means that superposition does not apply to circuits containing diodes. When a voltage is applied across a resistor, current flows in proportion to the voltage where the proportionality factor is constant.

Diodes are semiconductor devices which might be described as passing current in one direction only. The latter part of that statement applies equally to vacuum tube diodes. Diodes however are far more versatile devices than that.

What happens when power is connected? ... If a battery is applied to the p-n junction so that the positive side of the battery is connected to the p-type side and the negative side of the battery is connected to the n-type the following occurs ... As a result current flows and the junction is said to be forward biased.

The simple function of a diode is to allow current to flow in one direction only. ... A diode performs this function by being constructed from a continuous piece of n-type and p-type material where the diode action takes place at the boundary of two materials. ... Shown above is a p-n junction. As soon as the two materials...

The nature of the p-n junction is that it will conduct current in the forward direction but not in the reverse direction. It is therefore a basic tool for rectification in the building of DC power supplies.
