Ohm’s law is a fundamental principle of electricity that states the current through a conductor between two points is directly proportional to the voltage across those points. This law is named after Georg Simon Ohm, who discovered it in 1827.
Ohm’s Law is a basic law that governs the flow of electricity in an electrical circuit. It can be used to calculate the power output of an electrical device or circuit, as well as how much resistance a wire has when it is being tested for current flow.
In essence, Ohm’s Law states that voltage (E) is directly proportional to the current (I) flowing through a resistor. The mathematical symbol for this law is E = I x R. When calculating the resistance of an object, it is important to use the correct units: ohms in SI units or watts in British thermal units (BTU). To calculate the power flowing through a circuit, use the power equation: P = VI x ITry all in one HVAC Business Software - Free - 1 User
