Understanding Ohm's Law and Its Components

Ohm's Law is a fundamental principle in physics and electrical engineering that describes the relationship between voltage, current, and resistance in an electrical circuit. The law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, and inversely proportional to the resistance (R) of the conductor. Mathematically, this is expressed as V = IR.

The Correct Answer: Resistance

According to Ohm's Law, the correct answer is Resistance. The formula for Ohm's Law is V = IR, where V is the voltage, I is the current, and R is the resistance. This means that voltage is equal to current multiplied by resistance.
