1. An NTC (Negative Temperature Coefficient) thermistor has a ß of 3631 (K) and a resistance of 10 k at a reference temperature of 25 °C. a) What is the resistance of the thermistor at 87 °C? b) When the control process has reached its operating temperature of 87 °C there is 17 V across the thermistor. What is the power dissipated? c) What possible phenomenon could this power dissipation lead to and what can be done to minimise it?

Depending on voltmeter/ammeter terminal connection to the components, you might find different signed voltage and currents values for the same component. This causes different signed power values for the same components therefore we cannot state whether components generate or absorb power. What is your solution to this chaos? **please type it using keyboard NOT handwriting**
