Problem

An electrical appliance takes

900\,\text{W}

of average power when connected to a

230\,\text{V}

50\,\text{Hz}

mains supply. If the power factor of the appliance is

0.60

(lagging), the rms current drawn from the mains is closest to a)

4.6\,\text{A}

3.9\,\text{A}

6.5\,\text{A}

2.4\,\text{A}
