Shocking Vocab!
Current
a flow of electrical charge carriers, usually electrons or electron-deficient atoms. The common symbol for current is L
Power
is the rate (energy amount per time period) at which work is done or energy converted. The scientific unit of power is the watt (W), which is equal to one joule (energy amount) per second (time period).
Resistance
the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation. Ohm's law resistance (measured in ohms) is equal to the voltage divided by the current.
Conductors
are materials that permit electrons to flow freely from particle to particle
Semiconductors
are the foundation of modern electronics. Semiconducting materials exist in two types - elemental materials and compound materials.
