Ohm’s Law Calculator (Voltage, Current, Resistance, Power)
Understanding the fundamental principles of electricity is essential for anyone working with electrical systems. Ohm’s Law is a cornerstone of electrical engineering and physics, relating voltage, current, resistance, and power in a simple and effective manner. With our Ohm’s Law Calculator, you can easily compute any of these four essential quantities, making it an invaluable tool for students, electricians, and engineers alike.
What is Ohm’s Law?
Ohm’s Law states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) of the conductor. The law can be summarized by the formula:
V = I × R
Where:
- V = Voltage (Volts)
- I = Current (Amperes)
- R = Resistance (Ohms)
