The diagram shows a temperature sensing circuit used to control a heating system in a house.
What quantity does the ammeter measure? (One correct word only needed)
(a)
What is the name of the component connected in parallel with the Voltmeter
(a)
What will happen to the reading on the Ammeter if the temperature of the Thermistor increases?
It will remain the same because all the compenent have not changed
The current will go down because the R of the thermistor increases
The Current will go up beacuse the R of the thermistor decreases
