Electrician vs Operational Amplifiers Pro

Thank you for using Electrician. Your care, skill, and attention to detail deserve tools that help you stay organized. Whether you are learning the trade, checking a circuit, or recording measurements, keep building on what you know with electrical calculators and practical references close at hand. Electrician brings electrical math, RF calculations, unit conversions, and saved records into one app. Find a tool, enter your values, check the units, and keep the context behind your work. It is a useful companion for electricians, apprentices, electronics technicians, and anyone who works with circuits. 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. RECORD THE DETAILS THAT MATTER - Create a record from Home and give it a useful 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 that need another look. - Duplicate a record when you need a similar starting point. - Return to a previous result without relying on memory. SEE YOUR SAVED WORK MORE CLEARLY - Review record totals and recently updated entries. - Compare the number of records in each category. - Check which records are flagged for follow-up. - See record activity over time. - Review field completion and tracked numeric values. - Explore charts that put your saved measurements in context. REFERENCES AND EVERYDAY 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 when a project calls for cutting calculations. A WORKFLOW YOU CAN MAKE YOUR OWN - 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. START FREE, ADD PRO WHEN YOU NEED IT 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. Bring your experience, check your inputs, and keep a useful record of the result. Your next calculation is a good place to start. For monthly subscriptions: Monthly Pro is a 1-month auto-renewable subscription. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
