Question

An electrical load operates at 120 Vrms . The load as an average of 8 kWbsorb at lagging power factor of 0.8 The effective current 1 rms is

Answer 1

$\bigstar$

Given

120 V rms

 8 kW. absorbed power

Power factor i.e $Cos(\varnothing)$ =0.8 

$\bigstar$

$\boxed{P = V_{RMS}\times I_{RMS}\space cos(\varnothing)}$

$\implies$

$\boxed{I_{rms}= {8000\over 120\times0.8}}$

$\implies Answer$

$\boxed{ I_{RMS}=83.33 A}$
