Across
- 5. the SI unit of electrical resistance, expressing the resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt.
- 6. a form of energy resulting from the existence of charged particles , either statically as an accumulation of charge or dynamically as a current.
- 8. an electromotive force or potential difference expressed in volts.
- 10. a substance which does not readily allow the passage of heat or sound.
- 11. the rate of flow of electric charge.
- 13. a path along which the whole current flows through each component.
- 15. a path between two or more points along which an electrical current can be carried.
- 16. a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.
Down
- 1. a characteristic of a unit of matter that expresses the extent to which it has more or fewer electrons than protons.
- 2. the SI base unit of electrical current.
- 3. the SI unit of electromotive force, the difference of potential that would drive one ampere of current against one ohm resistance.
- 4. comprises branches so that the current divides and only part of it flows through any branch.
- 7. a measure of the opposition to current flow in an electrical circuit.
- 9. a material or object that permits an electric current to flow easily.
- 12. a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
- 14. he quantity of electricity transported in one second by a current of one ampere.
