@Black-menace.
3ph curr = 8A which is for per phase. If 1 phase (2 wires), So 2*8 = 16.

Why for single phase=2*3phase current?

The proper choice of a resister to determine a wanted current flow in a particular circuit is knows as effective resistance.

What is the meaning of effective load ?
Is it in star or delta and the factor must be sqrt (3).
