Answer / anand_gupta112001

Amperes when horsepower is known

1) HP x 746/E x Eff x pf (for single phase)

2) HP x 746/1.73 x E x Eff x pf (for 3 phase)

Amperes when kilowatts are known
3) Kw x 1000/E x pf (for single phase)

4) Kw x 1000/1.73 x E x pf (for 3 phase)

Note: I = Amperes; E = Volts; Eff = Efficiency; pf = Power Factor; Kva = Kilovolt-amperes; Kw = Kilowatts

Answer / sureshkumar balakrishnan

In AC Single Phase: P=V*I*PF

In AC Three Phase: P=1.732*V*I*PF

In DC: P=V*I

P(KW)=Load or Power, V=Voltage, I=Current, PF=Power Factor.
