Direct current (DC)is when electricity only flows in one direction.

Direct current is produced by electrical cells, batteries and dynamos.

Direct current can be made from an alternating current using a diode.

Direct current is needed to charge a cell or battery.

Direct current is used in electrolysis.


This is a constant direct current from a 3V battery.	This is a fluctuating direct current.	This is the direct current caused by mains electricity being passed through a diode.	This is the direct current caused by mains electricity being passed through a Rectifier which is a set of diodes.
