1)
In general, resistor's resistance depends (slightly) on the temperature of the resistor, with the relationship depending on the details of the material. Do you expect the temperature of a resistor to increase or decrease as you run more current through it? Based on this relationship and your results from Part IV, how does the light bulb's resistance depend on temperature?
2)Where can you apply a diode? Give one example of where it can be used?

What is the relationship between the moles of solute and the
mass of solute?
Rewrite the molality expression in terms of grams and molecular
weight.
Background:
Properties that depend on the concentration of particles in solution are called colligative properties. The number of particles in a solvent can affect the freezing or boiling point of solvent. To express the effect of concentration on freezing point or boiling point, molality is used in place of molarity. Molality (m) is the number...

Calibration and sensing Consider a thermistor temperature sensor (Fig. 1) with a pull-up resistor R1 connected to a 10-bit analog-to-digital (ADC) converter (a full scale No-210-1=1023 counts corresponding to the reference voltage Vref). The thermistor is used to measure temperature in the total input span from -10°C to 110°C. knots n(t VO R1 A/D GND Temperature Fig. 1 The output count of the thermistor measurements circuit can be modeled by a nonlinear function of...

(3) Re-read the Introduction, giving particular attention to its final paragraph. Now, suppose that physical considerations lead you to expect that measurements on a certain thermodynamic system will lead to the following relationship between the pressure p and the temperature T p %(kT) where k is a constant. Pressure measurements are taken on the system as the temperature is varied, and you would like to perform a curve fit on this data in order to measure the constant k. As...
