1 amp with 10 ohms, = 10 volts, 10 amps with 10 ohms, = 100 volts, use our amps to volts calculator to convert amperes in voltage.
The calculator uses Ohm’s Law to perform this conversion, which states that voltage (V) is equal to current (I) multiplied by resistance (R).
- A 5-amp current flowing through a 10-ohm resistor, the calculator would determine that the voltage is 50 volts.
- In a circuit with 2 amps of current and 25 ohms of resistance, the calculator would show a voltage of 50 volts.

Amps to Volts Conversion Formula
The formula for converting amps to volts is derived from Ohm’s Law:
V = I × R
Where:
- V is voltage (in volts)
- I is current (in amperes)
- R is resistance (in ohms)
To convert amps to volts, you need to know the resistance in the circuit. If you know the power (P) instead of resistance, you can use the formula:
V = P ÷ I
Using V = I × R:
Current: 3 amps
Resistance: 15 ohms
Voltage = 3 × 15 = 45 volts
Using V = P ÷ I:
Current: 2 amps
Power: 100 watts
Voltage = 100 ÷ 2 = 50 volts
How to convert amps to volts?
- Determine the current (I) in amperes.
- Identify the resistance (R) in ohms or the power (P) in watts.
- Apply the appropriate formula:
- If you know resistance: V = I × R
- If you know power: V = P ÷ I
- Calculate the result to get the voltage in volts.
Convert 4 amps to volts, given a resistance of 20 ohms.
Current (I) = 4 amps
Resistance (R) = 20 ohms
Use V = I × R
V = 4 × 20 = 80 volts
Convert 5 amps to volts, given a power of 600 watts.
Current (I) = 5 amps
Power (P) = 600 watts
Use V = P ÷ I
V = 600 ÷ 5 = 120 volts
How many volts is 20 amps?
- Current (I) = 20 amps
- Resistance (R) = 5 ohms
- Use V = I × R
- V = 20 × 5 = 100 volts
20 amps flowing through a 5-ohm resistor results in 100 volts.
It’s important to note that the voltage would be different if the resistance changed. For instance, if the resistance were 10 ohms, the voltage would be 200 volts (20 × 10 = 200).
How many amps in 240 volts?
Voltage (V) = 240 volts
Power (P) = 2880 watts
Use I = P ÷ V
I = 2880 ÷ 240 = 12 amps
A 240-volt circuit consuming 2880 watts of power would have a current of 12 amps.
