Potential Dividers
Cards in this deck (6)
- 1Example of a potential divider circuit :
- 2Potential divider circuits have at least....2 resistors
- 3If a component has a higher resistance, it means the voltage will be....Also higher
- 4—As temperature decreases, resistance of the thermistor increases
Therefore it's share of voltage also increases (shares larger proportion)
So the heater is connected in parallel to get a higher voltage in order to turn on (as voltage in parallel = same)
- 5—As temperature increases, resistance of the thermistor decreases
Therefore the resistor will share the larger proportion of total voltage
So the fan is connected in parallel to the resistor to receive a higher voltage when hot
