About this app

Electrical Calculations is the best app in the electrical sector, it has many calculations that can help you in your work. It can not miss in your smartphone!

Main calculations:
Wire size, voltage drop, current, voltage, active / apparent / reactive power, power factor, resistance, Maximum wire length, Current carrying capacity of insulated conductors / bare conductors / busbar, Conduit fill, Sizing the circuit breaker, Admissible let-through energy of the cable (K²S²), Operating current, Reactance, Impedance, Power factor correction, Power factor correction of transformer MV/LV, Capacitor power at different voltage, Earthing system, Short circuit current, Conductor resistance, Calculation of the cable temperature, Power losses in cables, Temperature sensors (PT/NI/CU, NTC, Thermocouples…), Analog signal values, Joule effect, Fault current of strings, Risk assessment of overvoltages with atmospheric origin.

Electronic calculations:
Resistor / Inductor color code, Fuses, Sum resistors / capacitors, Resonant frequency, Voltage divider, Current divider, Zener diode as voltage stabiliser, Resistance to reduce voltage, Resistance for led, Battery life, Primary/Secondary winding of transformer, Antenna length, CCTV Harddrive/Bandwidth calculator.

Calculations concerning the motor:
Efficiency, Motor from three-phase to single-phase, Capacitor start motor single-phase, Motor speed, Motor slip, Maximum torque, Full-load current, Diagrams of the three-phase motor, Insulation class, Motor connections, Motor terminals marking.

Conversions:
Δ-Y, Power, AWG/mm²/SWG table, Imperial / metric conductor size comparison, Section, Length, Voltage (Amplitude), sin/cos/tan/φ, Energy, Temperature, Pressure, Ah/kWh, VAr/µF, Gauss/Tesla, RPM-rad/s-m/s, Frequency / Angular velocity, Torque, Byte, Angle.

lots of formulas, calculators, etc... . seems like it could be excessive and too wide ranging for any one individuals needs, but i suppose better too much than too little. . .. would like to be able to play with a few features that don't have the lock key symbol next to them, but when i click on them I'm taken to pop up screens soliciting for purchase of the app. probably more an oversight than a nag. would've liked to have seen one or two of the definitions just to see the format, but they're all locked (example -surely unlocking ohms law definition wouldn't be an issue - I'm sure anyone looking at an app like this already knows it by heart).

Useless. Don't bother. I uninstalled it within 5 minutes. Can't use any features without getting bombarding with full-screen ads every time you try to calculate something. You need to dismiss the ads before you can see each result. The impedance calculator is worthless, it's only a series/parallel R-equiv calculator. There aren't any fields to input C, L, or Freq values. It literally can't do the most basic RLC calculations. Garbage.

Just got the paid version. Good app but I thought for all that money that it would show you how it calculated its values as well as giving you an answer. Yes you can go off looking for the formulas. Especially when you print off your calculations. All it does is basically does a screenshot with input values and result. Does not show you how it got to the value through formulas so no evidence to back up your print out. Shame, think that is the only thing it's lacking. Maybe future update?
