Ohm's Law

Ohm's law is a mathematical relationship of three variables in an electronic circuit containing a resistive element. It states that the voltage across a resistive element is equal to the current passing through the resistive element times the resistance of the resistive element. The law is named after German physicist Georg Ohm, who wrote a treatise on this relationship in 1827.

In mathematical terms, this is written as:

<math>V = IR</math>

Where

<math>V</math> Voltage across resistive element

<math>I</math> Current through resistive element

<math>R</math> Resistance of resistive element
