Electrons 1 of 12 In circuits, diodes are to do with what? Direction 2 of 12 In circuits, thermistors and resistors are to do with what? Resistance 3 of 12 Ohm's Law states... Resistance is directly proportional to temperature 4 of 12 Is copper low or high resistance? Low 5 of 12 If a wire is long and thin, what will the resistance be? High 6 of 12 If a wire is short and thick, what will the resistance be? Low 7 of 12 A filament bulb is... An Ohmic device 8 of 12 What happens as more bulbs are added to a series circuit? Each one gets dimmer 9 of 12 In a series circuit, to find the potential difference/resistance/cell voltage, what do you have to do? The sum of each component gives the total 10 of 12 What happens as more bulbs are added to a parallel circuit? Each one stays the same 11 of 12 In a parallel circuit, to find the total current, what do you have to do? The sum of each component gives the total 12 of 12
