engineering
Solve for voltage, current, or resistance using V = I × R.
V = I × R ⇔ I = V / R ⇔ R = V / I ⇔ P = V × I

engineering
Read a 4-band resistor from its color bands.
R = (10·d1 + d2 + d3) × 10^multiplier (5-band adds a 3rd digit)
Calculate - 🧰
engineering
Combine resistors in series, parallel, or a custom mix.
Series: R = Σ Rᵢ; Parallel: 1/R = Σ 1/Rᵢ
