ElectroCalc Pro vs BenchKit

ElectroCalc Pro is the essential utility for electronics engineers and hobbyists. Simplify your daily circuit calculations with this powerful tool. [Key Features] 1. Basic Electronics - LED Resistor Calculator - Voltage Divider Calculator (Vin, R1, R2, Vout) - LM317 Voltage Regulator Calculator 2. Power & Cables - Ohm's Law Calculator (Voltage, Current, Resistance, Power) - AWG (American Wire Gauge) Table & Conversion 3. Battery Tools - Battery Runtime Calculator - Battery Configuration Calculator (Series / Parallel) 4. PCB Tools - PCB Trace Width & Resistance Calculations

BenchKit puts four everyday electronics calculations in one focused, offline iPhone app. RESISTOR COLOR BANDS Decode 4, 5, and 6-band axial resistors. See the nominal resistance, tolerance range, and temperature coefficient where applicable. PCB TRACE WIDTH Estimate minimum internal or external copper trace width from current, copper weight, and allowed temperature rise. Results are shown in millimeters and mils. VOLTAGE DROP & POWER Check line voltage drop, delivered voltage, resistive power loss, and retained voltage. VOLTAGE DIVIDER Calculate ideal unloaded output voltage, divider current, total dissipation, and Thevenin resistance. No account. No ads. No analytics. No network connection. English, Simplified Chinese, and Japanese. BenchKit is a quick estimation tool. Always verify production designs against component datasheets, applicable standards, simulation, and physical validation.
