Voltage is a measure of the pressure, or electromotive force applied to make electrons

14.
is defined as electrons flowing between two points
having a difference in voltage potential.
15.
Current is measured in

George Ohm, a German physicist, made an important discovery about electricity in the
early 19th century. He found that in many materials, especially metals, the
that flows through a material is proportional to the
across the
material.

Ohms Law can be written as Voltage (Volts) =

Electrical power is the
