1.   A powerful electric current is passed through a piece of graphite.

2.   We cannot examine all water to see if, when an electric current is passed through it, at one electrode hydrogen is given off, at another oxygen.

3.   As the bullet leaves the gun, a battery passes a current through the coil, generating a magnetic field in the cylinder.

4.   During the procedure, an electrical current is passed through the needles, apparently disrupting normal pain signals by stimulating local nerves.

5.   Electric currents were passed through the ground, at depths of a few feet.

6.   Fluorine, a poisonous pale yellow gas, is normally prepared by passing a current of electricity through molten fluoride salts.

7.   He had discovered that by passing electrical currents through muscles, they could be stimulated into involuntary contraction.

8.   The film could be removed with electrolytic cleaning, in which an electric current is passed through the oxide molecules, the method apparently proposed by Timet.

9.   A very high current is then passed through the cathode, causing the metal to gradually creep along the surface of the substrate and adhere to it.
