What is Ohm's Law?
Understand the Problem
The question is asking for a definition or explanation of Ohm's Law, which is a fundamental principle in electrical engineering and physics relating voltage, current, and resistance.
Answer
Ohm's Law: V = IR, where V is voltage, I is current, and R is resistance.
Ohm's Law is a fundamental principle in electronics which states that the electric current through a conductor between two points is directly proportional to the voltage across the two points. It is expressed with the formula V = IR, where V is the voltage, I is the current, and R is the resistance.

More Information
Georg Simon Ohm, a German physicist, formulated Ohm's Law in 1827. It is fundamental for understanding how electric circuits operate.
Tips
A common mistake is confusing the units. Remember, volts measure voltage, amperes measure current, and ohms measure resistance.
