Across
- 3. A current that flows always in one direction
- 8. An electrical component that limits or regulates the flow of electrical current in an electronic circuit
- 12. A circuit having more than one path for current flow
- 13. The pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop
- 15. The voltage across a conductor is directly proportional to the current flowing through it provided all physical conditions and temperatures remain constant
- 17. A circuit that comprises a path along which the whole current flows through each component
- 18. An object which is capable of producing magnetic field and attracting unlike poles and repelling like poles
- 22. A branch of Physics that deals with the
- 24. force that occurs between electrically charged particles
- 26. The region around a magnetic material or a moving electriccharge within which the force of magnetism acts
- 27. The rate at which work is done and/or energy is transformed into an electrical circuit

- 30. A unit of measurement of the rate of an electron flow or current in an electrical conductor
- 31. Measurement unit of the resistance in the SI which is defined as the resistance that allows the circulation of a current of an ampere when a potential difference of one volt is applied to it
Down
- 1. Is a measure of the ability of water to pass an electrical current
- 2. For a given electric conductor, what is the name given to the ratio potential difference applied divided by current produced
- 4. It is the flow of electricity in an electronic circuit and to the amount of electricity flowing through a circuit
- 5. Like poles repel one another and unlike poles attracteach other
- 6. Its magnetism is 'always on' it generates its ownpersistent magnetic field
- 7. It is when a single resistance replaces the combination of resistances without h changing the current in the circuit
- 9. Is divided into two rules which are the junction rule and the loop rule
- 10. Any energy source devices that use energy, and conducting wires that connect the two terminals of the battery to the two ends of the light bulb
