Electrical Calculator vs Tensora

Electrical Calculator is your all-in-one app for fast, accurate, and essential electrical calculations. Packed with 60+ powerful tools, it's designed for electricians, electrical & electronics engineers, and students. Every calculator includes built-in formulas and supports both USCS and SI units. What's New: • Category filters — find any calculator in seconds with purpose-based groups: Ohm's Law, Wiring & NEC, Power & Phase, Motors, Transformers and more • Refreshed design with a cleaner look Core Calculators: • Voltage, Current, Resistance & Power (Ohm's Law) • kVA to Amps / Amps to kVA (Single & Three Phase) Electrical System Calculators: • Voltage Drop Calculator (per NEC/IEEE standards) • Wire Size Calculations (AWG & mm²) • Power, Current & Horsepower (DC, Single & Three Phase) • Efficiency & Power Factor Calculators • Neutral Current (3-Phase Unbalanced Loads) Transformers & Generators: • Transformer Current, Voltage & Resistance Imbalance • DC Generator Reactance & Impedance: • Inductive & Capacitive Reactance • Resonant Frequency • Characteristic Impedance (Parallel & Coaxial) • Impedance Calculators (R-L-C combinations) Series / Parallel Calculations: • Resistance, Inductance & Capacitance (Series & Parallel) • Unknown Resistance & Capacitance (Series & Parallel) Components: • Resistor Color Code — resistance to color bands and back • Inductor & Capacitor Sizing Formulas Lighting & Energy Tools: • Luminous Intensity, Luminous Flux & Solid Angle • Energy Cost Calculator • Energy Stored in Resistors, Inductors & Capacitors Conversions: • Star ↔ Delta Conversion • Field Strength & Electrical Potential • Resistance, Resistivity, Conductance & Conductivity • Capacitance, Inductance & Charge Density Converters • Power Converter Key Features: • Category filters for fast navigation • Flexible unit selection for inputs and outputs • Full iPad support with split view • Dark Mode and 12 languages • Clean interface for the field, the shop, and the classroom

Setlist Lab compares several tuning stages against one captured instrument setup. See per-string tension, range outliers and pitch changes between songs before changing a real instrument. HOW TO USE THE UPGRADE 1. Open Setlist and capture the current instrument, scale lengths, strings and reference pitch. 2. Add tuning stages and enter pitches for every string. Review stage totals, string values and moves between stages. 3. Save the setlist. Prepare a CSV with the pitches, unit weights, gauge sources and calculated values. The tension calculator, tuning library, personal ranges, string finder and comparison tools remain available. Native tabs put Setlist beside the calculator; additional tools are grouped under Explore. WHAT TO KNOW One to eight stages with matching string counts; up to 50 saved setlists. Results use the app catalog and its interpolated unit weights. Estimates do not establish neck, bridge or string safety and do not apply changes to your instrument. The earlier all-fourths gauge study is a simplified model; its assumptions differ from Setlist Lab. iPhone and iPad. No account required.
