What does picojoule per second represent?

Picojoule per second is a power unit indicating an energy rate of one trillionth of a joule per second, useful for describing very low continuous power levels.

What is volt ampere used for?

Volt ampere quantifies apparent power in AC electrical circuits, reflecting the combined effect of voltage and current without considering phase differences.

Why is the conversion from pJ/s to V*A relevant?

It helps relate micro and nano-scale continuous power measurements to apparent power parameters used in AC system evaluations like transformer ratings and circuit protection.
