About this app

Electrical Field Calculator is an Android utility app for quickly handling calculations often needed in electrical and electronics work.
You can use power calculation, fuse sizing, LED resistor calculation, resistor color code decoding, and capacitor calculation in one place.

It is designed for field workers, technicians, electronics users, and students who want to continue basic electrical calculation workflows without switching between multiple calculator apps.

Main features:
- Power calculator for voltage, current, power, and resistance relationships
- Fuse sizing calculation based on load type
- LED resistor calculation based on supply voltage, LED forward voltage, and target current
- Resistor color code decoding for 4-band, 5-band, and 6-band resistors
- Capacitor reactance and series/parallel equivalent capacitance calculation

Use Electrical Field Calculator when you need quick, repeatable electrical and electronics calculations in one place.
