Ohm's Law Calculator

Apply Ohm's law V = I·R and power equations P = V·I = I²R = V²/R. Solve for any two unknowns given the others. Works for DC circuits and AC circuits using impedance Z in place of R.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Apply Ohm's law V = I·R and power equations P = V·I = I²R = V²/R. Solve for any two unknowns given the others. Works for DC circuits and AC circuits using impedance Z in place of R

Each component has a specific meaning:

  • Impedance Z in place of R — The impedance z in place of r recorded for the patient or scenario being assessed.

Note: Interpret the ohm's law result against the clinical thresholds and context described above.

How to Use

Enter the impedance Z in place of R for the patient or scenario you are assessing. Apply Ohm's law V = I·R and power equations P = V·I = I²R = V²/R. Solve for any two unknowns given the others. Works for DC circuits and AC circuits using impedance Z in place of R. Use the ohm's law result to inform your clinical assessment.
