Ohm's LawX

Enter any two values. While entering your 2nd value the remaining values will be calculated for you.

Current (I) | Amps | |

Power (P) | Watts | |

Resistance (R) | Ohms | |

Voltage (V) | Volts | |

Formula Reference

I = V ÷ R = P ÷ V = √P ÷ R

P = V x I = V^{2} ÷ R = I^{2} x R

R = V ÷ I = P ÷ I^{2} = V^{2} ÷ P

V = I x R = P ÷ I = √P x R

I = V ÷ R = P ÷ V = √P ÷ R

P = V x I = V

R = V ÷ I = P ÷ I

V = I x R = P ÷ I = √P x R
