Blue & it goes left 6 of 16 What colour is the Live wire? Brown/Red & it goes right 7 of 16 What colour is the Earth wire? Green Stripes & it goes in the centre 8 of 16 Equation for Work done Work done = voltage x charge 9 of 16 In parallel; what happens to p.d/voltage & current? P.d/Voltage is equal & current is shared1 10 of 16 Equation for Voltage Voltage = Current x resistance 11 of 16 What is direct current? Flows in one direction; always flows in one direction 12 of 16 What is alternating current? Constantly changing which leads form positive to negative constantly 13 of 16 What current & p.d does the National Grid use? Low current & High p.d 14 of 16 What are step up tranformers? These step up the voltage 15 of 16 What are step down transformers? These step down the voltage 16 of 16
