The response time is the time taken by a sensor to respond to a change in input.
When a sudden temperature change was applied, the bead thermistor was able to respond to it 3 times faster than the thermistor probe, therefore comparatively, its response time is very rapid.

Conventional current flow was deemed to go from the positive pole of a battery, given the symbol ( or vet) to the negative pole, given the symbol ( or vet).
Physics Thermistor Coursework Solving Verbal Problems
Of course, electrical current only ever flows when there is some kind of electrical connection or circuit joining these two poles of the battery.The graph below illustrates this fact: Operating over a range of -200°C to 1000°C, they are supplied in glass bead, disc, chips and probe formats.NTC thermistors should be chosen over PTC thermistors when a continuous change of resistance is required over a wide temperature range.A suitable circuit might contain a component known as a resistor, given the symbol R which has a property known as resistance which restricts or cuts down current flow and gets warm or hot in the process.Note the difference between wire in the practical set up diagram which may be curved or straight or take whatever route and the diagrammatic representation of wires in the circuit or schematic diagram which are by convention always shown as straight lines.C Electricity flowed in exactly the opposite way which we now know to be true.In other words they defined what is still known to this day as Conventional Current Flow.Why does its resistance decrease when temperature is increased?When the thermistor is subjected to an increase in temperature, the number of electrons able to move about and carry charge increases - it promotes them into the conducting band.For the second experiment, I performed a similar kind of experiment, but from a different sort of perspective.In this case, instead of using a liquid medium with varying temperatures, I have used a source of heat which releases a reasonably constant and significant amount of heat.
