level questions: electrical ciruits
| Question | Answer |
|---|---|
| in a series ciruit.... | current is the same everywhere, so if there are 10 ammeters on a series circuit it will read the same reading. |
| in a series circuit.... | voltage of the indiviudual componenets adds up to the total voltage, if one voltmeter reads 4V and aother reads 7V the total voltage is 11V |
| in a parallel circuit | voltage is the same everywhere, so if there is 10 voltmeters in parallel they all read the same reading |
| in a parallel circuit | current of individual components adds up to the total current, if one ammeter reads 4A and another reads 18A then the total resistance is 22A |
| light dependant resistars | resistance decreases |
| thermistors | temprature increases, used in fire alarms |
