For humans, we know that water and electricity . are . not good to mix. For some animals, this safety concern about electricity is not a problem. In fact, they survive because they can use electricity in the . Made by. Abhishek. Walter Paul. 11104EN072. INTRODUCTION. Modern . power system are growing fast with . more generators. , transformers and large network in the system. whenever a fault occurs there is a need for the protection of these system. Here we discussed the use of superconductor as protective device for surge current protection. Superconductors conduct electricity, offering zero resistance below certain temperature. We study different types of superconductor as fault current limiter and their working. Learning Outcomes. Distinguish between alternating and direct current.. State . the frequency of UK mains electricity.. Describe . how the potential of the live wires varies each cycle.. State . that the potential of the neutral wire is approximately . A) 1 m/s.. B) 1 km/s.. C) 10 m/s.. D) the speed of light.. E) 1 mm/s.. 2) When a current flows through a metal wire, the moving charges are. A) positive metal ions.. B) negative metal ions.. C) only electrons.. The return current neutralizes the current carried by accelerated electrons as they stream from the acceleration region in the corona to and through the hard X-ray source region in the lower transition region and chromosphere. . Electric Current. Electric current . – The net movement of electric charges in a single direction through a wire or conductor.. Voltage difference . – The force that causes electric charges to flow; charges flow from high voltage to low voltage.. NOTE: I will be plugging grades now, if you have tasks not turned in including projects, please turn them in ASAP before the end of the Second Period today.. . Those who have finished all tasks can move on to today’s tasks..
