Electricity

3. The opposition to the flow of electric current, determined by a material's geometry and composition. Measured in Ohms.
4. The rate at which electrical energy is transferred by an electric circuit. Measured in Watts
8. A material (like rubber or glass) that resists the flow of electric charge because its electrons are tightly bound to their atoms.
9. Current Electric current that flows in only one constant direction.
12. A passive two-terminal electrical component that implements electrical resistance as a circuit element.
13. A material (like copper or gold) that allows the free flow of electric charge due to loosely bound electrons.
15. Current Electric current that periodically reverses direction and changes its magnitude continuously with time.
16. Law The principle that the current through a conductor between two points is directly proportional to the voltage across the two points (V = IR).

1. A device used to store electrical energy by accumulating charge on two closely spaced surfaces insulated from each other.
2. Field A region around a charged particle where a force would be exerted on other charged particles.
5. Charge A physical property of matter that causes it to experience a force when placed in an electromagnetic field. Measured in Coulombs.
6. The rate of flow of electric charge past a point in a circuit. Measured in Amperes.
7. Electricity An imbalance of electric charges on the surface of a material, usually caused by friction.
10. Circuit A circuit configuration where components are connected end-to-end, providing only one path for the current to flow.
11. Also known as Electric Potential Difference; it is the work done per unit charge to move a charge between two points. Measured in Volts.
14. Circuit A circuit configuration where components are connected across the same two nodes, providing multiple paths for the current.
