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.

In mathematical terms, this is written as:

$V=I*R$

Where

V: Voltage across resistive element

I: Current through resistive element

R: Resistance of resistive element
