About this app

Electrician provides electrical math, RF calculations, unit conversions, references and saved records for electricians, apprentices, electronics technicians and other people who work with circuits. Enter values, check units, and save measurements with their context.

ELECTRICAL CALCULATIONS

– Solve Ohm’s law for voltage, current, or resistance.
– Calculate power in watts from voltage and current.
– Find current or voltage from known power values.
– Work out resistor power and voltage drop across a resistor.
– Calculate parallel resistance and tolerance ranges.
– Explore transformer turns ratios and reflected impedance.
– Choose input units where available to suit your measurements.

COMPONENTS, RF, AND SIGNALS

– Calculate capacitor and inductor reactance.
– Work with resistor and capacitor impedance.
– Convert between dBm, watts, and RMS voltage.
– Explore attenuation, return loss, and mismatch loss.
– Review reflection coefficient and VSWR results.
– Find tools for time, frequency, geometry, and statistics.
– Use the expression calculator for additional formula work.

RECORDS

– Create a record from Home and give it a title.
– Keep values, units, notes, and tags together.
– Add custom values for work that needs extra context.
– Edit records with automatic saving as you work.
– Search titles, notes, tags, and saved values.
– Filter records by type, flagged status, or recency.
– Flag items for follow-up.
– Duplicate a record to use it as a starting point.
– Return to a previous result.

RECORD STATISTICS

– Review record totals and recently updated entries.
– Compare the number of records in each category.

– Review field completion and tracked numeric values.
– Explore charts of your saved measurements.

REFERENCES AND CONVERSIONS

– Open bundled drill-size, tap-drill, and pipe-thread charts offline.
– Browse links to electrical, cable, and engineering references.
– Convert feet, yards, and meters.
– Convert miles and kilometers.
– Work with U.S. gallons, Imperial gallons, and liters.
– Convert square inches and square millimeters.
– Convert cubic inches and cubic centimeters.
– Open machining tools for cutting calculations.

SETTINGS AND HELP

– Choose an appearance in Settings.
– Open Help for formulas, workflows, and tool guidance.
– Keep inputs and results visible, or collapse supported sections.
– Check for an available App Store update from Settings.
– Use notes to explain the conditions behind a measurement.

FREE AND PRO ACCESS

The free version includes a limited number of successful calculations and records per type. Pro removes those limits and adds sharing, import, export, and email support from Help. Monthly and lifetime purchase options are available in the app.

With Pro, export saved data and its links as JSON, or export a selected category as CSV for a spreadsheet. JSON archives exclude attached image files and app preferences. Transfer limits apply; see Help for details before backing up or moving data.

Check your inputs and units before using a result.
