Solve for Voltage (V), Current (I), Resistance (R), and Power (P) from any two knowns.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Choose your two known variables (e.g. Voltage & Current, or Resistance & Power).
Type the numeric values into the parameter inputs.
Inspect the solved electrical parameters across all 4 quadrants.
V = I × R (Voltage = Current × Resistance), and P = V × I (Power = Voltage × Current = I² × R = V² / R).
Voltage is in Volts (V), Current in Amperes (A), Resistance in Ohms (Ω), and Power in Watts (W).
