What is the mathematical relationship between voltage, current, and resistance? What is this relationship called?
Understand the Problem
The question is asking about the mathematical relationship that relates voltage, current, and resistance, specifically looking for the name of this relationship.
Answer
Ohm's Law: V = I * R.
The mathematical relationship between voltage, current, and resistance is defined by Ohm's Law: V = I * R. This relationship states that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R).
Answer for screen readers
The mathematical relationship between voltage, current, and resistance is defined by Ohm's Law: V = I * R. This relationship states that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R).
More Information
Ohm's Law was established by the physicist Georg Simon Ohm in the 1820s. It is widely used in calculating electrical values within circuits and is fundamental in electrical engineering.
Tips
A common mistake is reversing the formula to V = R * I; always remember it's V = I * R. Also, ensure units are consistent when applying the formula.
