Differential Amplifier
Wolfram Research
A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages, but suppresses any voltage common to the two inputs.

Ohm's Law
Wolfram Research
The current through a conductor between two points is directly proportional to the voltage across the two points. It is inversely proportional to the resistance across those two points.
