Ohm's Law Calculator is a flexible tool that determines the relationship between voltage, current and power. All you need to do is type in the two parameters and find the unknown parameter easily in the blink of an eye.
What is meant by Ohm's Law?
Ohm's Law denotes the relationship between electric current and potential difference. As per Ohm's Law Potential Difference between two point in the circuit is directly proportional to the current passing through the circuit as well as the resistance of the circuit.
Ohm's Law Formula
Ohm's Law is one of the basic laws of physics and explains the relationship between voltage, current, power. Ohm's Law Formula can be used to determine the resistance as a quotient of voltage and current. It can be written as R = V/I where R is the Resistance, V is the Voltage, I is the Current. Resistance is expressed in units Ohms and is named after the Georg Ohm the inventor of Ohms Law.
Ohms Law is applicable for substances that induce power such as metals and ceramic. However, it has an exception for semiconductors, isolators. It is only valid under certain conditions such as fixed temperature.
Physicscalc.Com has got concepts like friction, acceleration due to gravity, water pressure, gravity, and many more along with their relevant calculators all one under one roof.
Finding Voltage is one of the fundamental ones in Ohms Law. We can rewrite the formula shared above to get the Voltage i.e. V= IR. You can calculate the voltage if you aware of current, resistance easily by simply substituting them in the above formula. Units of Voltage are Volts.
