chegg compare the ratio of the line and phase voltages and currents for parts 1 and 2. do the ratios support the theory? compare the ratio of the line and phase voltages for both the primary and secondary for parts 3 and 4. do the ratios support the theory? 3. compare the ratio of the primary and secondary line voltages and also the phase voltages for parts 3 and 4. do the ratios support the theory?
