9. The amount of current that will operate an overcurrent protective device is inversely proportional to A. resistance. B. voltage. C. time. D. capacitance.

Compare alternative and direct currents by comparing their physical properties. (Explain alternans, cycles, periods, frequency terms during this comparison. Also in this comparison, explain the electron flow directions separately in alternating and direct current)

Discuss the importance of voltage regulation in power systems.
