Answer:
Ohm's law is the most important,
basic law of electricity. It defines the relationship between the three fundamental electrical quantities: current, voltage, and resistance.
1. An electric current
is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.
2. Voltage,
electric potential difference, electric pressure or electric tension is the difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points.
3. RESISTANCE
the act or power of resisting, opposing, or withstanding. the opposition offered by one thing, force, etc., to another. Electricity. Also called ohmic resistance
