(not a battery) must be a complete circuit, there must be no short circuits. 1 of 10 What is an electric current? a flow of electric charge. 2 of 10 How do you calculate current? I = Q ÷ T, I is the current in amps, Q is the chagre in coulombs, T is the time in seconds. 3 of 10 What is potential difference messured in? measured in Volts. 4 of 10 How do you calculate potential difference V = W ÷ Q, V is potential difference, W is the work done in joules, Q is the charge in Coulombs, 5 of 10 What is thecdifference between a battery and a cell? A battery is a collection of cells. 6 of 10 What does an Ammeter look like? Ammeter; 7 of 10 What does a lamp look like? Lamp; 8 of 10 What does resistance mean? A measure of how much a component resists the flow of elecricity. 9 of 10 What is a filament lamp? Filament lamps contain a thin metal filament that glows when electricity passes through it. 10 of 10
