Show you work. All answers should be given with two decimal places. 1. A current of 3.33 mA (IMA -0.001A) passes through a resistor which is at a temperature 22.3 °C. As a result, a voltage of 3.00 Volts is generated across the resistor. Calculate the resistance of the resistor in k 2. Rrom 2. Now the same resistor as in question 1 is immersed in liquid nitrogen (T--195.8 °C). The voltage across the resistor is still 3.00V but the...
