For the circuit shown below determine whether the load Z0 is

For the circuit shown below, determine whether the load Z_0 is capacitive or inductive under the following conditions: the power factor is 0.76 leading the power factor is 0.5 lagging i_0(t) = cos wta v_0 (t)5 cos wtV i_a (t) = 10 cos(wt-pi/4)a v_0(t)=50 cos wt

Solution

a) since power factor is leading the load is capacitive in this case

b)since power factor is lagging the load is inductive in this case

c)there is no phase difference between voltage and current in this case that is V and I are in phase so the load impedance resistive in this case

d) current is 45 degree out phase so the load is inductive in this case
