The circuit diagram below shows a 12 V battery of negligible internal resistance connected to a
2 combination of three resistors and a thermistor.
(a) When the resistance of the thermistor is 5.0 kΩ
(i) calculate the total resistance of the circuit,
total resistance = ......................................... kΩ
(3)
(ii) calculate the current in the battery.
current = ........................................ mA
