About

RCircuitCalc

This app helps engineers and students design electrical and electronic circuits by calculating standard resistance values based on E-series numbers. It supports various circuit types, including voltage dividers, series, parallel, and combination circuits, and can also calculate current and power for each resistor.

Highlights
  • Calculates standard resistance values
  • Supports voltage dividers, series, parallel, and combination circuits
  • Calculates current and power for resistors
  • Outputs resistance values based on E-series numbers (E6, E12, E24, E48, E96)
  • Calculations based on input voltage, output voltage, current, and resistance ratio

This application is intend for engineers and students who are wasting time for designing electric and electronic circuits. The standard resistance values based on E-series numbers are outputted in inputting necessary conditions such as input voltage, output voltage, current and so on. Features The calculable circuits are as follows: - Voltage Dividers (Inputting output voltage or resistance ratio) - Series Circuits - Parallel Circuits - Combination Circuits In the Voltage Dividers, resistance values are calculated in entering input voltage, output voltage or resistance ratio, and current into input boxes, besides, the most suitable resistance values are calculated in selecting priority whether Normal or Vout. In the Series Circuits, Parallel Circuits and Combination Circuits, divided resistance values are calculated in entering a combined resistance value into an input box. Calculated resistance values are displayed with the following E-series number specified either. E6, E12, E24, E48, E96 This application is able to calculate current and power of each resistor on calculated resistance values. Attention Because standard resistors are used and precision of calculation is ensured, the following restrictions are set up. - Range of resistance value: 1Ω ~ 10MΩ - Range of resistance ratio: 0.1 ~ 10

Verdict

The call

The clearest difference is review sentiment: KNIPEX at 100% against RCircuitCalc's 0%. KNIPEX also leads on price (Free vs $1.99) and rating (4.9 vs 1.0). RCircuitCalc's advantage is device support (3 vs 1) and iOS requirement (13.6 vs 16.4). On ads and in-app purchases there is nothing between them.
