A source of potential difference 1 of 12 What is electric current? The rate of flow of electrical charge 2 of 12 In most circuits , what is the charge that flows to carry the current? Electrons 3 of 12 What is the word equation for flow of charge? charge flow = current x time 4 of 12 What is the symbol equation for flow of charge? Q = l t 5 of 12 What is the unit of charge? Coulombs , C 6 of 12 What is the unit of current? Ampenes , A 7 of 12 At any point in a single closed loop , the current... is the same. 8 of 12 The current through any component depends on... the resistence ( R ) of the component and the potential difference ( V ) across it. 9 of 12 What is the definition of resistence? The amount that a component opposes the flow of current 10 of 12 What is the unit of resistance? Ohmns , Ω 11 of 12 What is the alternative term for potential difference , that means the same thing? Voltage 12 of 12
