Question:
A series resistive inductive load is energised from a 240V (RMS), 50Hz single phase AC supply, such that the load draws 1200W at a power factor of 0.8.
a) Calculate the reactive power and the current supplied to the load.
b) Sketch a phasor diagram for this load condition, showing all circuit voltages and currents.
c) Calculate the capacitance value (μf) required to be placed in shunt with the RL load so as to achieve unity power factor as seen by the supply.
A sign of uniform density weighs 270 lb and is supported by a ball-andsocket joint at A and by two cables. Determine the tension in each cable and the reaction at A.
