CH 17 – Current and Resistance
... In metals the voltage is proportional to the current over a wide range of current and voltage and R is constant. In this case the equation above is referred to as ‘Ohm’s law’. In some materials or devices the voltage is not proportional to the current and the material or device is said to be non-oh ...
