The most obvious hazard is electrical shock, where a current passes through part of the body.

In a series circuit, the same current passes through a series of components.

An unblown fuse lets current pass, and acts as a one.

But when the current passes through there is tremendous movement in that apparently inert mass.

An electric current passes through a solenoid, resulting in a magnetic field.

Do you realize how much current passes through here?

For example there are things like a diode which will let current pass in only one direction.

In this circuit, the current passes through the electrodes on both ends of the tube.

At the same time, a dozen pulses of electric current pass through the mesh.

The process during which the current passes through tissue produces heat that kills cells in the surrounding area.
