Across
- 2. A unit of measurement for electrical resistance to a current.
- 3. A loop-shaped path through which electric current travels from the source through some device using electricity, such as a light-bulb, and back to the source.
- 4. A completed, low-resistance circuit that allows electrons to follow a shorter, unintended path back to the power source rather than follow the longer path that goes through the load.
- 7. To connect any part of an electrical wiring system to the ground or to another conducting body, such as a metal water pipe or a metal rod driven into the earth.
- 9. A solid state device that converts alternating current to pulsed direct current.
- 11. The opposition against the free transfer of electrons in a conductor. Measured in ohms.
- 12. A unit of potential difference, or a unit of measurement of electrical pressure or force. Abbreviated V.
Down
- 1. The difference, measured in volts, in electric potential between two points, especially two points in an electric circuit.
- 5. A resistor built so that the current traveling through the circuit can be adjusted at will. Volume controls and dimmer switches are examples.
- 6. A substance or device through which electricity passes.
- 8. A unit measuring the strength of an electrical current, based on the number of electrons transferring past a given point per second. Abbreviated amp.
- 10. Unit that measures electrical power at the point where it is used in a circuit. Abbreviated W.
