Ohm's law
Videos
Ohm's law states that the electric current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resist

Voltage, also known as potential difference, electric pressure, or electric tension, is the difference in electric potential between two points. In a static electric field, it corresponds to the work
Batteries are sources of voltage in many electric circuits.
