mainly potassium current
When a pn junction is reversed bias practically no current flows through it ,but a very small current flows through due to minority charge carriers ,which is known as reverse saturation current .In p type due to electrons and in n type due to holes .

To be precise, a current doesn't flow - a current "is". Although many people - including myself - often use the informal term "a current flows". The particles that make up the current do flow - or move. An electrical current involves the movement of some type of charged particles. Often, these are negative electrons, but there are other possibilities, as well, especially positive holes, and negative or positive ions.
Power Factor of an electrodynamometer can be improved by connecting a large resistor in series with the current coil.

Direct current
Alternating current changes polarity 50 0r 60 times a second depending on the country you are in.
The field winding in the stator is exposed to the full current generated by the rotor's winding.
Alternating current
One type of insulator is ceramic, these were used in the older power lines and the newer styles are glass
One example of current electricity are transmission lines. These bring electricity from power stations to individual houses.
