Physics
Across
- 4. The electric potential difference between two points.
- 5. A device to transform energy from one electrical circuit to another by means of mutual inductance between two coils.
- 6. Property of space around a charged object that causes forces on other charged objects.
- 8. The rate at which a charge flows through a surface.
- 9. The ratio of potential difference across device to current through it.
- 10. The moving part of a rotary electrical switch in certain types of electric motors or electrical generators that periodically reverses the current direction between the rotor and the external circuit.
- 11. The production of electric field or current due to change in magnetic flux.
Down
- 1. A single resistance that could replace several resistors.
- 2. A region within a magnetic material in which the individual magnetic moments of the atoms are aligned with one another and they point in the same direction.
- 3. The flow of electric charge periodically reverses direction.
- 7. The two ends of a magnet
- 12. Space around a magnet throughout which magnetic force exists.
- 13. A device that uses an electric current to produce a concentrated magnetic field.
- 14. The unidirectional flow of electric charge.
