**Attempt :**

Firstly , I used (2.4 kW - 1.5 kW) to find the power that the second load draws . Secondly I used the formula : P = V rms I rms pf in order to find the I rms current supplied from the source and then the second load , which is around 7.32 Amps . However , when i used the same formula to find the pf i.e

900 / (120 * 7.32 ) , I realised that the power factor exceeds 1 . May I know what I have done wrongly ?

Thanks in advance.
