_Voltage_ is the electrical potential. It is similar to water pressure in a
pipe. Voltage is polarized, and relative, therefore it is often measured with
respect to the earth, or _ground_. A parallel circut always has the same
voltage across all components.
_Current_ is the flow of electricity. It is similar to water flow in a pipe.
Current is not polarized, and not relative. A series circut always has the same
current across all components.
