a) A 140-V rms, 60-Hz source is applied to a load impedance Z. The apparent power entering the load is 160 VA at a power factor of 0.654 lagging. i) Calculate the complex power. ii) Find the rms current supplied to the load. iii) Determine Z. iv) Assuming that Z = R + jw L, find the values of R and L.
