Answer the following statement(s) true (T) or false (F)
1. Semiconductor materials exhibit a change of resistance with a change of temperature and have a positive temperature coefficient.
2. A semiconductor material’s resistance will increase with an increase of temperature.
3. Junction diodes can be used as temperature sensors by passing a constant current through them and measuring the voltage drop across the PN junction.
4. Since semiconductor materials have a negative temperature coefficient, an increase of temperature will produce an increase in voltage across the diode.
5. Since semiconductor materials have a negative temperature coefficient, an increase of temperature will produce an increase in voltage across the diode.
