Ohm's Law
From Conservapedia
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:
Where
Voltage across resistive element
Current through resistive element
Resistance of resistive element
