What does volt ampere (V*A) represent?

Volt ampere is the unit of apparent power in AC circuits, calculated as the product of RMS voltage and RMS current, representing total delivered power regardless of phase angle.

When does volt ampere equal watts?

Volt ampere equals watts only when the power factor is 1, which corresponds to a purely resistive load.

Why convert volt ampere to microwatt?

Converting to microwatts allows measurement of very small power levels suited for ultra-low-power devices, precision instrumentation, and scientific analysis.

Tips & Best Practices

Ensure the power factor is considered if converting apparent power to real power measurements.
Use microwatt units primarily for very low power levels to maintain measurement relevance.
Double-check context-specific needs when applying this conversion in sensitive biomedical or microelectronic device testing.

Limitations

Volt ampere measures apparent power and only equals watts at a power factor of 1, so conversion to microwatt assumes real power equivalence when used.
Microwatt scale is intended for very small power, making conversions from high volt ampere values potentially less meaningful without scale adjustment.
