1. A 230V, 50Hz supply feeds a load of 50 in series with a 50mH inductor. Sketch the load
voltage and load current waveforms. What is the time difference between the zero crossings of
voltage and current, and which occurs first? What is the power factor?
4.1 Assume that the breakdown strength of the dielectric insulator in a coaxial
cable is Eb and outer radius is fixed at R2. Determine the radius of the inner
conductor in order that the cable can carry maximum voltage.
