Ohm’s Law is a fundamental principle in electrical engineering and physics, describing the relationship between voltage, current, and resistance in an electrical circuit. It 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 between them.
Ohm’s Law can also be extended to include the concept of electrical power. Power in an electrical circuit is the rate at which electrical energy is converted to another form of energy, such as heat, light, or mechanical energy. The unit of power is the watt (W).
What is Ohm's Law?
Ohm’s Law (E = IR) is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.
The full forumal is E = I x R where E = Volts, I=current (in amps), and R=resistance. This is also sometimes annoted as voltage = current x resistance, or volts = amps x ohms, or V = A x Ω.
