    I am taking Electrical Circuits in my Technology school. I am stuck on the following problem:

    A 440 V 60 Hz parallel ciruit consists of a motor that draws 10 kVa with a power factor of 0.7071 lagging (load 1) and a load that dissipates 10 kW (load 2).

    a. What is the overall power factor for the circuit?

    b. What is the value of the reactance, and how must it be connected to the circuit to connect the power factor to 1.00?

    Not sure what 'lagging' power factor is and how to handle dissipate load.

    Appreciate any help that will show my how to calculate the values.

    construct your power triangles, then add or subtract your like units as required.
