ma to voltage calculator
Convert milliamp current (mA) to voltage using Ohm’s Law. Enter current and resistance to find voltage instantly for electronics and circuit design.

resistance current voltage calc
To change the mA into an equivalent voltage value, convert the measured current in mA to amps by dividing the milliamps current by 1000 then multiply this value by the resistance in ohms using Ohm Law.
Formula & Table Summary:
- I_mA = Current in milliamps
- R = Resistance in ohms
- V = Voltage in volts
current sense voltage calc
Calculate the voltage generated with the milliamp current with Ohm Law. To obtain electronics and current loop voltage calculations, enter mA and resistance.This calculator is useful in 420 mA current loop systems, signal conditioning and the design of electronic circuits to find an output voltage given an input current and resistance.
milliamps volts converter
| Current (mA) | Resistance (Ω) | Voltage (V) |
|---|---|---|
| 20 | 250 | 5.0 |
| 10 | 100 | 1.0 |
Frequently Asked Questions - ma to voltage calculator:
What is an mA to Voltage Calculator?
It converts milliamp current and resistance to voltage using Ohm’s Law.
What formula converts mA to volts?
V = (I_mA / 1000) × R.
Why convert mA to volts?
To determine voltage drop or signal output in circuits.
Do I need to convert mA to A first?
Yes, divide mA by 1000 to get amps.
What is 20 mA through 250 Ω?
5 volts.
Can I use this for 4–20 mA loops?
Yes, it’s ideal for current loop voltage calculations.
Does resistance affect voltage?
Yes, higher resistance produces higher voltage for the same current.
Can mA be negative?
Yes, in AC or reverse current situations.
Is this valid for AC and DC?
Yes, with RMS values for AC.
