• Ohm’s Law (V/I/R/P)
• LED Resistor Calculator (Vs, Vf, If)
• Capacitor Decoder (3-digit & EIA codes)
• Voltage Divider (2 or 3 resistors)
• RC/RL Time Constant with charging curve & key points (1τ…5τ)
• Unit Converter (Ω, F, H, Hz + prefixes)
• Battery Life Estimator (battery type, load current, duty cycle)
• Transistor Reference (NPN, PNP, MOSFET) with fast search & filters

Notes

• Designed for speed, clean UI, and offline use.
• Reference values may vary by manufacturer—always confirm with the datasheet.
