A $230\: V$ rms source supplies power to two loads connected in parallel. The first load draws $10 \: kW$ at $0.8$ leading power factor and the second one draws $10\: kVA$ at $0.8$ lagging power factor. The complex power delivered by the source is
- $(18 + j\:1.5)\:kVA$
- $(18 – j\:1.5)\:kVA$
- ‘$(20 + j\:1.5)\:kVA$
- $(20 – j\:1.5)\:kVA$
