OhmsLab: Ohms Law & Codes is one of the focused apps from InnovaLabWorks. It does one job well, works offline, and keeps your data on this device. It does not use cloud sync, and there is no account to create or service to sign up for.
What you can do with OhmsLab: Ohms Law & Codes
- Ohm's law and power: enter any two of voltage, current, resistance or power and get the other two
- Resistor color decoder: 4, 5 and 6 band, with tolerance and temperature coefficient, drawn on a real resistor
- Find the colors for a value: enter a resistance and see the bands
- LED series resistor: from supply, forward voltage and current, with the nearest standard value and a power rating
- Series and parallel: combine any number of resistors, both totals at once
- Voltage divider: output voltage, current and power, plus a helper to size R2 for a target output
- Save any calculation to your bench and reopen it live
- Bench reference: the full color code table, SI prefixes and the Ohm's law relationships
- Copy any result, clean dark bench interface
