Across
- 2. the energy of either an object in motion or the energy that is stored in objects by their position
- 4. an electromechanical measuring instrument for electric current
- 9. comprises branches so that the current divides and only part of it flows through any branch
- 10. an electric current which periodically reverses direction and changes its magnitude continuously with time
- 11. the physical interaction among electric charges, magnetic moments, and the electromagnet a type of magnet in which the magnetic field is produced by an electric current.
