ELECTRICITY IN THE HOME 0.0 / 5 ? PhysicsElectricityGCSEAQA Created by: BootsyCreated on: 07-11-17 16:59 What are the 2 types of energy supply? Alternating and direct 1 of 8 How are alternating currents produced? By the alternating voltages in which the positive and negative ends keep alternating 2 of 8 What is direct current? A curent that is alwasy flowing in the same direction which is created by direct voltage 3 of 8 What are the 3 types of wire in a cable? Live wire, Neutral wire and Earth wire 4 of 8 What is a live wire? The live wire is brown and provides the alteranting potential difference from the mains supply 5 of 8 What is a neutral wire? It is blue and completes the circuit and carries away current 6 of 8 What is an earth wire? It is green and yellow and it protects the wiring and for saftey it stops the appliances casing from becoming live 7 of 8 If you touch a live wire what happens? A large potential difference is produced across your body and a current flows through you casuing a large electric shock 8 of 8
