Ohm's Law & Circuit Calculator
scienceSolve Ohm's law (V, I, R, P) and calculate equivalent series and parallel circuit resistances.
Ohm's Law & Electric Power
Formulated by Georg Ohm in 1827, Ohm's law states that current through a conductor between two points is directly proportional to the voltage across the two points: V = IR. Electric power is given by P = VI = I²R = V²/R.
