Voltage describes electrical potential difference
It represents how much energy per unit charge is available between two points.
Current is charge flow
Electric current measures how rapidly charge passes through a point.
Resistance affects current
Materials and components oppose current to different degrees.
Circuits need complete paths
A break in the conductive path prevents steady current through that branch.
