AV-E05
Ohm's Law Calculator
Solve V, I, R and P from any two, size a voltage divider, or pick an LED series resistor and its power rating.
● Runs on your device; nothing is uploadedHow to use it
- Choose Ohm's law and power, Voltage divider or LED resistor.
- For Ohm's law, enter any two of V, I, R and P; the last two edited are used.
- For a divider, pick Find Vout or Find R2 and enter Vin, R1 and R2 or Target Vout.
- For LEDs, enter supply and forward voltage, current, LEDs in series and a series.
- Copy any value from the Result panel.
Limits
- Suggested power rating
- 1/8 W to 10 W, with at least 2× margin
Features
- Solves V, I, R and P from any pair
- Divider R2 rounded to the nearest E6–E96 value, with the resulting Vout
- LED resistor rounded up to a standard value so current stays at or below target
- Results in engineering notation with SI prefixes
