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 current passing through a resistive element is proportional to the voltage across the resistive element and inversely proportional to the resistance of the resistive element.

In mathematical terms, this is written as:

$I={\frac {V}{R}}$

Where

I: Current through resistive element

V: Voltage across resistive element

R: Resistance of resistive element
