What does 1 Volt ampere represent in AC circuits?

It represents the unit of apparent power, calculated as the product of RMS voltage and current, reflecting total delivered power regardless of phase angle.

How is joule per hour related to watts?

One joule per hour equals 1/3600 of a watt, quantifying power as energy transfer per hour instead of per second.

Why must power factor be considered when converting from V*A to J/h?

Because volt ampere measures apparent power including reactive components, direct conversion assumes power factor equals one to represent actual energy transfer.
