What does volt ampere measure in AC circuits?

Volt ampere quantifies apparent power as the product of root-mean-square voltage and current, representing total delivered power regardless of phase.

Why convert volt ampere to microjoule per second?

The conversion helps express apparent power in very small units suitable for measuring low continuous power in microelectronics and photonics.

Are there limitations to this conversion?

Yes, the conversion captures power magnitude but not phase information and is best for steady-state conditions, not transient effects.
