While a (BJT) can be simplistically thought of as two diodes with a shared terminal (anode for the PNP variety), the transistor polarity is usually expressed based on the prevalence of in the parts of the device: for the regions where the charge flow is primarily due to the electrons (free due to the presence of ), and for the regions where the flow is mostly due to (available spaces for additional electrons.

In thermal power stations, mechanical power is produced by a that transforms , often from of a , into rotational energy. Most thermal power stations produce steam, so they are sometimes called steam power stations. Not all thermal energy can be transformed into mechanical power, according to the ; therefore.
