When current flows in a conductor you do not get an electric shock provided you do not touch the conductor.
That's a "direct" current.
Alternating Current could fit this description in this question.
electric current
When an electrical current flows through a wire it creates what is called an Electro Magnetic Field.A magnetic field is create when an electric current flows through a wire.
A magnet created when electric current flows through a coil of wire is called an electromagnet.
the current which flows in only one specific direction is called as unidirectional current
because it flows on the direction where the net charge flows. :D
In one direction - or constant - is called direct current. The other sort is called alternating current.
Not all current flows in the same direction because electric energy does not follow the circular flow of electricity which results to direct and alternate current.
The ELECTRONS flow from the negative to the positive terminal. But it is considered that the electric current flows from the positive to the negative terminal.
One distinction that is often made is between DC (direct current, flows in one direction) and AC (alternating current, changes direction many times per second).
