Advanced Interactive Ohm's Law Calculator
Theory & Formulas: Ohm's Law
Ohm's 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 between them. This relationship is fundamental in electrical circuits.
- Voltage (V): Electrical potential difference, measured in Volts (V).
- Current (I): Rate of flow of electric charge, measured in Amperes (A) or Amps.
- Resistance (R): Measure of the opposition to current flow in an electrical circuit, measured in Ohms (Ω).
The primary formulas derived from Ohm's Law are:
- To find Voltage: V = I × R
- To find Current: I = V / R
- To find Resistance: R = V / I
