What is Ohm's Law?
Understand the Problem
The question is asking for the definition of Ohm's Law, which is a fundamental concept in electrical circuits relating voltage, current, and resistance.
Answer
Ohm's Law defines the relationship between voltage, current, and resistance in an electrical circuit.
Ohm's Law defines the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. The law states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance.
Answer for screen readers
Ohm's Law defines the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. The law states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance.
More Information
Ohm's Law is expressed mathematically as V = IR, where:
- V is the voltage across the conductor in volts.
- I is the current flowing through the conductor in amperes.
- R is the resistance of the conductor in ohms.
Tips
A common mistake is to confuse the relationship between the variables. Remember that voltage is directly proportional to current, while resistance is inversely proportional to current.
