What D is 2 independent layers of insulating material over live conductors? . What C throws a switch when excess current is detected?. What T is piece of equipment used to reduce 240 volt to 110volts?. What I means the physical disconnection of the electric supply from the source of electrical energy?. What C is the flow of electrons along a conductor?. What O is electrical resistance measured in?. What R determines how much current flows through a component?. What V is the difference in potential between 2 points in a circuit? . What A is when a current may jump through air to a person or equip close to high voltage conductors?. What E is a path for electricity to flow to ground from a conductor in a fault condition?. What C is a substance through which electricty flows?. What S is a build up of electrons on weak electrical conductors or insulating material?. What C is where electrical equipment and a power supply are joined together?. What R is a protective device which monitors and compares the current flowing and cuts off supply?. What F is a thin piiece of wire which will melt when excess current passes through it ?. What I is a covering which encloses a live conductor?. What S is a fault that occurs when current does not flow through all the components it should?.
