Problem

A circuit takes a current of

3\ \text{A}

at a power factor of

0.6

lagging when connected to a

115\ \text{V}

50\ \text{Hz}

supply. Another circuit takes a current of

5\ \text{A}

at a power factor of

0.707

leading when connected to the same supply. If the circuits are connected in series across a

230\ \text{V}

50\ \text{Hz}

supply, calculate: (a) The current (b) The power consumed (c) The power factor
