The Calculations You Do Every Day
Electrical engineering is calculation-heavy. Not complex calculus — but constant, repetitive arithmetic that interrupts your design flow. A dedicated calculator gives you zero friction between needing a value and getting it.
Key Calculators
- ▸Ohm's Law — V=IR, solve for any variable plus power calculations
- ▸Voltage Divider — Vout = Vin × R2/(R1+R2)
- ▸RC Time Constant — τ = R×C, time to charge/discharge
- ▸Low-Pass Filter — fc = 1/(2π×R×C)
- ▸LED Resistor — R = (Vsupply - Vforward) / Iled
- ▸Inductor Impedance — XL = 2π×f×L
