11.   It tests DNA as any substance would be tested for conductivity, by applying an electrical potential across it and seeing how much current flows.

12.   Its Spanish name is an allusion to the Christ child, because the warming current often flows near South and Central America around Christmas time.

13.   New Age enthusiasts note, with straight faces, that Sedona spelled backwards is Anodes, the conducting surfaces through which electrical current flows.

14.   Rinaldo and Rodriguez-Iturbe took as a hint the way that electrical current flows through a complicated set of wires and resistors.

15.   That eliminates the AC losses, and the current can flow over long distances virtually without any energy loss.

16.   The currents would flow between the star and the planet, carried by the ionized gases surrounding the star.

17.   These social currents flow in direct opposition to the rising power of Christian right forces that want to engulf any gains made by gays.

18.   These, the hot and neutral, allow the current to flow through an appliance and return to the ground, making an electrical circuit.

19.   Wattage, which is calculated by multiplying the voltage by the current flowing in a wire, measures the work being done at a given point and time.

20.   When a hair dryer is dropped into a tub, some current flows through the water.
