The resistance of a NTC resistor decreases with temperature. NTC resistors can therefore be used for temperature measurements. Another application is “soft start” circuits where the NTC resistor changes from high to low resistance as it gradually heats up from the dissipated power.
The NTC covers a temperature range of -55 ° C and +125 ° C.
On the plate, three NTC resistors a 470 Ω are mounted in parallel connection to increase the maximum power.
Place it in series with e.g. a 6 V 0.5 A incandescent lamp (pygmy bulb). Connect the series connection to 9 V. Observe, how the current increases while the NTC resistor gets hot. (Caution: Watch your fingers – the components get very hot.)
Mounted on a solid base with 4 mm safety sockets. A stable solution that will not tip over or slip in use.
Base: 120 x 90 mm.
