| 16297771648 | what way does the conventional current flow? | from positive to negative | 0 | |
| 16297792174 | What way do electrons flow? | from negative to positive | 1 | |
| 16297823145 | which components will only allow current to flow in forward bias? | LED and diode | 2 | |
| 16297899448 | What makes metals good conductors? | They have delocalised/conduction electrons which drift slowly along the wire | 3 | |
| 16297916558 | what is kirchoffs first law? | current and charge are always conserved | 4 | |
| 16297986662 | how is the movement of electrons through a metal described? | random as there is no overall net movement | 5 | |
| 16298018756 | why do electrons drift slowly through the copper lattice? | because they can only go a small distance before colliding with another atom | 6 | |
| 16298054018 | what has to be applied across the ends of a wire to cause current to flow? | potential difference | 7 | |
| 16298127104 | Why are insulators poor conductors? | they contain very few delocalised electrons | 8 | |
| 16298150949 | why do semiconductors undergo doping? | because this adds impurity atoms to improve their conductivity | 9 | |
| 16298198076 | what is the equation for EMF? | energy transferred over time | 10 | |
| 16298208689 | what is the equation for pd? | work done over time | 11 | |
| 16298239922 | What is Ohm's Law? | The current through an ohmic conductor (at a constant temperature) is directly proportional to the potential difference across the resistor. | 12 | |
| 16298321226 | what factors affect electrical resistance? | the material, its length, the cross sectional area and the temperature | 13 | |
| 16298520095 | what is resistivity affected by? | temperature | 14 | |
| 16298630810 | how do you convert from joules to kwh? | divide by 3600000 | 15 | |
| 16298646738 | how do you convert from kwh to joules | multiply by 3600000 | 16 | |
| 16298688704 | what is this a graph for? | a filament lamp |  | 17 |
| 16298668060 | what is this a graph for? | LED |  | 18 |
| 16298716823 | what is this a graph for? | resistor |  | 19 |
| 16298758839 | what is kirchoffs second law? | The total emf around a series circuit = the sum of p.d.s across each component. | 20 |
