Amps to VA Calculator
What is Amps to VA Converter?
Amps to VA Calculator is a power calculator that calculates the apparent power in VoltAmperes or VA in an electrical circuit, given its values in Amps and Volts. An important converter for professionals and hobbyists working with electrical systems, especially AC circuits, this provides the necessary power measurement.
The calculator works out the value for apparent power (VA) from given specific formulas in terms of the current value in amps. You can also convert amps to VA by using the following formulas.
Amps to VA Conversion
Formula: Amps to VA Conversion
To calculate the apparent power (VA) based on current (Amps) and voltage (Volts), use the following formulas:
For Single-Phase: \[ VA = I \times V \]
For Three-Phase (Line-to-Line): \[ VA = \sqrt{3} \times I \times V_{L-L} \]
For Three-Phase (Line-to-Neutral): \[ VA = 3 \times I \times V_{L-N} \]
Where:
- \(VA\) = Apparent Power in Volt-Amperes
- \(I\) = Current in Amps
- \(V\) = Voltage in Volts
- \(V_{L-L}\) = Line-to-Line Voltage for three-phase systems
- \(V_{L-N}\) = Line-to-Neutral Voltage for three-phase systems
Example Calculation (Single-Phase)
If the current is 5 amps and the voltage is 120 volts:
\[ VA = 5 \times 120 = 600 \text{ VA} \]
Example Calculation (Three-Phase, Line-to-Line)
If the current is 5 amps and the Line-to-Line voltage is 208 volts:
\[ VA = \sqrt{3} \times 5 \times 208 \approx 1.732 \times 5 \times 208 = 1801.6 \text{ VA} \]
Example Calculation (Three-Phase, Line-to-Neutral)
If the current is 5 amps and the Line-to-Neutral voltage is 120 volts:
\[ VA = 3 \times 5 \times 120 = 1800 \text{ VA} \]
How to Amps to VA Calculator?
Step 1: Select the type of calculation:
- Single Phase: For a standard circuit with one phase (e.g., household appliances).
- Three Phase (Line to Line): For industrial circuits with three-phase power (line to line voltage).
- Three Phase (Line to Neutral): For circuits with three-phase power and neutral voltage.
Step 2: Enter the current in amps (A) in the provided field.
Step 3: Enter the voltage in volts (V) based on the selected calculation type:
