Electrician Field Calc Toolkit

Electricians RF & Power Tools is a practical calculator suite built for electricians, technicians, and electronics professionals who need dependable answers in the field or at the bench. The app focuses on direct inputs, clear outputs, and formula-driven views that remove guesswork from power, impedance, signal, and conversion tasks.

The interface is organized into calculator sections so you can jump straight to the job:
- Math
- Power & Ohm’s Law
- RF / dB / Signal
- Impedance & Components
- Time / Frequency
- Geometry & Conversions
- Statistics
- Advanced RF / Transmission

Top workflow views are designed for fast solving:
- Ohm’s Law Smart Solver
- Power in Circuit
- dB Converter
- Return Loss / VSWR
- Reactance Calculator
- Impedance (RLC)
- Coax Cable Calculator
- Attenuator Designer
- Skin Depth
- Frequency / Wavelength / Delay

Power and circuit formulas included:
- Ohm’s law for voltage, current, and resistance
- Power from V×I, V²/R, and I²R modes
- Current from watts and voltage
- Voltage from watts and current
- Guided inputs that highlight the solved target

RF and signal calculation coverage:
- dBm to volts RMS
- Volts RMS to dBm
- Watts to dBm
- dB ratio to power and voltage scaling
- Attenuation from voltage ratio (20log) or power ratio (10log)
- Return loss, VSWR, mismatch loss, and reflection coefficient magnitude

Impedance and component tools:
- Capacitor reactance: Xc = 1/(2πfC)
- Inductor reactance: Xl = 2πfL
- RC series impedance magnitude and phase context
- RC parallel equivalent handling
- Parallel resistor total with tolerance min/max
- Transformer turns-ratio voltage and impedance relationships

Transmission and RF geometry tools:
- Coax characteristic impedance from diameters and dielectric constant
- Coax capacitance and inductance per meter
- Skin depth using frequency, resistivity, and permeability
- Frequency/wavelength conversion using propagation speed
- Cable delay from length and velocity factor
- Stub filter frequency estimator
- Air-core Wheeler inductance calculator

Engineering math and conversion tools:
- Binary and hexadecimal conversion
- Mean, sample standard deviation, min/max, median
- Percentage comparisons both directions
- Tolerance and ppm range calculations
- Circle area, circumference, rectangle area/perimeter
- Miles/kilometers, inches/millimeters, degrees/radians
- Period/frequency conversion and phase angle helpers

Built for daily use, not demo screens:
- Numeric text entry with units by field
- Guided “minimal inputs” layout in workflow views
- Instant output cards for quick reading
- Searchable calculator list
- Reset, randomize, and share results from each workflow
- Consistent formulas across iPhone and iPad layouts

Why this app works for real electrical work:
- You can verify power and resistor dissipation quickly
- You can check RF matching quality without separate tools
- You can estimate coax behavior before build or troubleshooting
- You can move from raw measurements to engineering values fast
- You can share calculation summaries directly from the tool

If you need a focused electrician/electronics calculator app with real formulas and clear view structure, Electricians RF & Power Tools keeps the workflow simple: enter known values, solve the unknown, and move on.

Formula behavior is designed for practical edge cases:
- Very small divisors are protected with safe minimums to avoid unstable divide-by-zero behavior
- Reflection coefficient entry is constrained to valid magnitude ranges for reliable VSWR/return-loss results
- Frequency and impedance dependent formulas stay consistent when switching between related tools
- Outputs are formatted for quick interpretation without hiding the underlying engineering relationship

For working electricians and electronics users, this means less manual calculator hopping, fewer transcription errors, and faster validation of power, RF, and component decisions during active work.
